The reactions at the end told the story. Everton were utterly delighted, and quite rightly - that could prove an enormous point for Sean Dyche's. Meanwhile, Chelsea's mini resurgence has been halted in its tracks ahead of the international break.
Report is below. Have a great evening. Adios.
Brilliant day of Premier League action
Saturdays of late have not been the most exciting generally, but today was utterly brilliant. Full results below.
Wolves 2-4 Leeds
Southampton 3-3 Tottenham
Aston Villa 3-0 Bournemouth
Brentford 1-1 Leicester
Chelsea 2-2 Everton
Report is to follow
The match report from Stamford Bridge is to follow shortly. Stay with us for that.
A rather telling stat, and an alarming one if you are of a Chelsea persuasion, that is the first time Everton have scored twice in a game since before the World Cup. Astonishing.
Chelsea 2-2 Everton
That was a brilliant second half, with Everton quite clearly the happier of the two sides. The away end is hailing the players with cries of 'Everton'.
What a moment that is for Simms, scoring his first goal for Everton and what a goal it is. Could Dyche have found the source of five or six goals that could be decisive in maintaining Everton's Premier League status?
Full-time: Chelsea 2-2 Everton
Some finish to this game. Chelsea have another corner, swung in from the right this time. Though Everton again head it clear, only as far as Fernandez... who has no time to shoot with England blowing his whistle.
Brilliant second half between two fairly limited sides.
90+3: Chelsea 2-2 Everton
McNeil takes down James on the right after being far too easily beaten. Should be careful, he was booked in the first half.
The free-kick is too clever by half, and Everton get it clear, though not well enough with Chelsea coming back again. Chelsea win a corner after Havertz's header deflects behind.
90+1: Chelsea 2-2 Everton
Chelsea come in search of a third goal having been pegged back twice. Havertz has an opening but his shot is scuffed.
Everton hack it clear, anywhere will do at this stage, though Chelsea come again and win another corner. It's swung in by Chilwell and Pickford shows bravery to come and punch.
GOAL: Chelsea 2-2 Everton
Wow. Just wow. Ellis Simms. His first goal for Everton, and it's some effort.
We had just been saying that Everton did not look like finding an equaliser, what do we know, eh? He picks it up on the right and beats James initially before knocking it past Koulibaly, showing brilliant strength and power to shake off the Senegalese and into the box.
Showing consummate coolness, he slips the ball under the legs of the onrushing Kepa and into the net. Cue pandemonium in the Shed End.
88': Chelsea 2-1 I Everton
Despite needing a goal, Everton aren't exactly doing much to try and get it. Their attempts to launch it long into the box just aren't working, and they don't really have the intricate players to pick the Chelsea defensive lock, which has looked more assured in the last two weeks.
Chilwell tries to release Havertz in down the left, but Everton win it back. It's then launched aimlessly up to the head of Simms, who can't reach it.
84': Chelsea 2-1 Everton
Chelsea have almost all of their players in their own half now, with only Joao Felix forward. Kai Havertz is sort of floating in a hybrid midfield-forward role. Everton are launching it long now to Simms and Gray.
Reece James does well to shadow the ball out of play for a goal-kick that is cheered loudly by the home crowd.
Felix is withdrawn for Chukwuemeka and Fofana, who received his first international call up this week, is replaced by Chalobah. Like-for-like swap at the back, while Havertz will now go up front with the former Aston Villa youth team player dropping into midfield.
82': Chelsea 2-1 Everton
Simms is on for Gueye, and he almost scores. McNeil picks the ball up on the left and drives a low ball across the face of the goal. It's neither a shot nor cross, but an Everton player could, and perhaps should, have got a touch there.
Swashbuckling run from Gallagher on the left sees him evade two, three, four Everton defenders before it deflects off him for a goalkick. Unlucky.
Coleman withdrawn for Mykolenko. Seven minutes to go, plus added time.
79': Chelsea 2-1 Everton
It hasn't been a great day for Everton in terms of results, with Leeds winning and Southampton rescuing a point from the unlikeliest of circumstances. They need something here.
Chelsea change with Kovacic replaced by Loftus-Cheek.
78': Chelsea 2-1 Everton
Reece James was booked in the melee that followed the penalty award.
Do Everton have two goals in them? Evidence this season would suggest not, given if they did score twice today that would be 10 per cent of all the goals they had scored in the league prior to this evening.
GOAL: Chelsea 2-1 Everton
Chelsea retake the lead. Exquisite penalty by Kai Havertz, cool as you like sending Pickford the wrong way before putting the ball high to the 'keeper's left.
Kai Havertz to take...
Oh no, oh no Everton. Have they shot themselves in the foot? James makes a dart into the box and he's brought down by Tarkowski. Stonewall.
71': Chelsea 1-1 Everton
Chelsea's main issue under Potter has been the players responding terribly to set backs. Think about the game at West Ham last month, or any of their recent defeats. They seem to lose confidence very easily. Will that happen here?
What do Everton do now? Stick or twist? A pulsating final 20 minutes, you would expect.
Doucoure is now playing much higher up, with Everton essentially playing with two up.
GOAL: Chelsea 1-1 Everton
Wow. 1-1. Doucoure.
Of course they find the equaliser from a set piece. The initial corner was met by Onana, but his header did not have enough purchase, deflecting out for another corner, this time from the opposite side.
McNeil swings it in and it's carnage in the box, with Chelsea failing to deal with it appropriately, and it finds the head of Doucoure on the left, around five yards from goal, and he heads it in! Fofana thinks he's got back to clear, but it crossed the line.
The away end went berserk, as you would expect.
66': Chelsea 1-0 Everton
The first half saw Gray play up front centrally, with his back to goal. That didn't work, so Dyche moved him to the right at half-time. He's been a bit brighter.
His best moment of the game comes as he stands Chilwell up and beats him for pace on the outside before sending a cross low with McNeil coming onto it. Kepa gets down well to claim.
However, his clearance is poor and Everton come again through Doucoure. He flicks it out to Godfrey on the left, and his cross is blocked by James for an Everton corner.
Gray to take from the right... ooo Onana has his head in his hands! He should score, but gets little meaningful contact. Another corner.
65': Chelsea 1-0 Everton
Dyche is in deep conversation with his two assistants on the touchline, seemingly regarding their first roll of the dice with substitutes. Their issue is that they don't exactly have goals on the bench, either, particularly with Neal Maupay as one of the options.
Chelsea are awarded a free-kick after Iwobi's boot was raised a little bit too high. No complaints, really.
63': Chelsea 1-0 Everton
Penny for the thoughts of Mykhailo Mudryk, who looks rather sad warming up on the touchline having not been selected to replace Pulisic.
Tarkowski is now screaming at the assistant referee on the far side after a throw in call went against him. Everton have around 25 minutes to find a goal, shouting at the officials is not going to help their cause.
Reece James is adjudged to have strayed offside after being found by Enzo Fernandez's long ball forward.
61': Chelsea 1-0 Everton
As far as it appears, it looks like Everton's issues, and perhaps the reason they might not survive, is their scant lack of goals. No team has scored fewer than their 20 this season, with Dyche's appointment having done little to alleviate the issues.
Conor Gallagher is introduced for Christian Pulisic. Chelsea will go to a 352 shape.
60': Chelsea 1-0 Everton
Dyche is unhappy about something, it looks like it's a tackle by Fernandez on Gray. Hmm, doesn't look like much.
58': Chelsea 1-0 Everton
Brilliant, brilliant delivery by Gray, but it evades everyone and goes out for a Chelsea goal-kick. Any touch, from an Everton or Chelsea player, and that was ending up in Kepa's net.
56': Chelsea 1-0 Everton
There's a different feel about Stamford Bridge now, it has been awakened by that goal.
Pulisic has the ball in the net but he's rightly adjudged to have strayed offside.
At the other end, Iwobi is taken out by Koulibaly who goes into the book. Looks harsh, that. But Everton have a free-kick on the right which they have to use if they want to get back into this game, you feel.
GOAL: Chelsea 1-0 Everton
Joao Felix. Brilliant finish from the best player on the park by some distance. Chelsea fling it to the left and it's knocked across by Chilwell and cut out by Tarkowski.
It falls to Felix on the left edge of the box, who takes a great touch to haul it out of the darkening early evening sky and sends a left-footed strike past the diving Pickford and in off the left-hand upright.
It says it all that a loan player, who doesn't have any sort of agreement in place to join the club on a permanent basis, has his own song.
Everton now have a mountain to climb.
52': Chelsea 0-0 Everton
Everton are showing a bit more adventure in this half. That said, it would have been practically impossible for them to show less.
They come forward through Gray on the right, his cross is cut out.
48': Chelsea 0-0 Everton
His second corner is much better, and almost sees Koulibaly nod it in. Everton head it clear, but it drops to James who strikes an effort which is blocked and sees Doucoure released with plenty of green grass ahead of him.
With all 10 of Everton's outfield players in the box defending the set piece, however, he has no options and his attempt to slip an on-rushing McNeil in is cut out by James.
At the other end, Pickford is forced into a pretty routine stop from Felix.
Potter and his assistant are getting animated about Everton's rather slow pace regarding going about things.
47': Chelsea 0-0 Everton
A rather tepid start to the half as supporters slowly trudge back to their seats after various half-time refreshments.
Chelsea get the ball forward to Joao Felix, who has been everywhere - in behind, on the left, right, in the pocket - and he switches it to James. He wins a corner. Chilwell stands over it. His out-swinger doesn't clear the first man. Poor.
46': Chelsea 0-0 Everton
Everton get us back underway. No changes for either side. The visitors would snap your hand off for a point, the hosts most definitely would not.
Story developing at Tottenham
Antonio Conte is going down swinging after watching his side surrender a two-goal lead to draw 3-3 at Southampton.
'They're used to it here. Don't play for something important. They don't want to play under pressure. They don't want to play under stress. Tottenham's story is this. 20 years there is the owner & they never won something. Why?' he said.
'Until now I tried to hide the situation. We can fight for what in this period, with this attitude, this commitment? For what? 7th? 8th place?'
Half-time: Chelsea 0-0 Everton
Chelsea's profligacy in front of goal continues. Everton do not look like they carry much of a threat, so one goal will conceivably do it.
45+3': Chelsea 0-0 Everton
Nearly, but not quite for Chelsea so far.
45': Chelsea 0-0 Everton
McNeil scythes down Fernandez on the edge of his side's box. He joins Gueye in the book.
Promising opportunity for Chelsea to take the lead on the stroke of half time, in what would be a real hammer blow to the visitors, who, if not well, have defended resolutely.
Havertz swings it in intricately and Fernandez comes onto it, but his shot is blocked.
We will have three minutes added on here. It hasn't been the worst half in the world, nor has it been the best. Somewhere in the middle.
43': Chelsea 0-0 Everton
Chilwell is down clutching his ankle. Replays show the ball just hit him there. Very odd.
Back underway. Two minutes to go until the break. Everton will not want to do what they did at Arsenal earlier this month, when they kept it tight for almost the entire half before capitulating in the final knockings.
41': Chelsea 0-0 Everton
Brilliant run from McNeil, his first positive involvement in this game, sees him carry the ball 50 yards and to the edge of the Chelsea 18-yard box. He beats three players, including Fernandez, though is met by Koulibaly as he shapes to shoot and the Senegalese's intervention sees it go out for a goal-kick.
40': Chelsea 0-0 Everton
Pulisic is back up after being hit in the chops by the ball. His first involvement since being allowed to re-enter the fray sees him pick the ball up from Fernandez around 40 yards from the Everton goal and turn.
As he does so, however, he sees a wall of pink and not much blue, meaning he's forced to turn back and Chelsea have to build again.
38': Chelsea 0-0 Everton
Half-time draws nearer and the two teams remain level-pegging at present. One side is trying to change that, one side, it could be strongly argued, are most definitely not.
35': Chelsea 0-0 Everton
Potter will be furious about that. Badiashile goes through the back of Gray around 30 yards from his own goal, gifting Everton a free-kick in the sort of position they absolutely adore.
Gray and McNeil stand over it, giants Keane and Godfrey are forward.
What a waste! McNeil shoots and sends it straight into the wall, hitting Pulisic's face. Ouch.
33': Chelsea 0-0 Everton
Very much one-way traffic so far in terms of possession and where the game has been played. That said, Chelsea haven't troubled Jordan Pickford at all. Their final ball has been off.
That said, Joao Felix has just stung the gloves of Pickford from the edge of the box on the right-hand side with a low drive straight at him after Chelsea broke following a rare Everton attack.
Tarkowski needs to be careful there, appearing to lash out at the Portuguese as they both ran towards the Everton goal. Not enough for VAR to intervene.
31': Chelsea 0-0 Everton
How long can Everton really stay watertight with the ball coming back this often? Half of them already look totally cooked.
They get a brief bit of respite after Havertz is adjudged to have fouled Tarkowski on the edge of the box. Loose definition of the word foul on evidence there.
29': Chelsea 0-0 Everton
Idrissa Gueye the first player to be booked after a rather heavy lunge on Pulisic, who has just recently returned from an ankle injury-induced lay-off.
Fofana is getting up and down in Chelsea's inside right-channel. Should both he and James stay fit, that could prove to be a really strong pairing on the Blues' defensive right-hand side in the months and years to come.
30 gone, no goals as yet. Chelsea have gone closest through Joao Felix. Everton haven't gone close really at all.
27': Chelsea 0-0 Everton
Ooo, so close for Chelsea. Joao Felix again. He is an absolutely brilliant player. He turns Tarkowski with consummate ease but his touch in doing so is just slightly too heavy and Everton manage to shovel it clear.
Though Chelsea come again, this time through Pulisic, who has been on the periphery thus far.
26': Chelsea 0-0 Everton
Demarai Gray has just dropped about halfway into his own defensive half to try and pick the ball up. He receives it from Iwobi with Fofana up the back of him and does well to hold onto it under increasing pressure.
Everton win a free-kick as a result of the Frenchman's rather overzealous attempts at winning the ball back.
23': Chelsea 0-0 Everton
That is the danger Everton can pose from a set piece. Pickford launches a free-kick from half-way which Chelsea, initially, get clear before Gray heads it back in.
Risky defending from Fofana sees the ball go straight out of play, but under pressure from Tarkowski, Potter would surely rather he wasn't so casual.
Everton showed last weekend at Forest what problems they can cause you from set plays. Chelsea beware.
20': Chelsea 0-0 Everton
Closest any side has come. Chelsea release Chilwell down the left, who finds Havertz. He sort of has a cross-cum-shot which almost finds Joao Felix, just a few yards out. Any - meaningful - touch and he scores there.
Chelsea are knocking on the door.
Meanwhile, Manchester City's FA Cup sixth round clash with Burnley is underway at the Etihad. You can follow that by clicking on the link below.
18': Chelsea 0-0 Everton
That is exactly the sort of quick, incisive play that Chelsea fans want to see from their team.
They play out again, this time down the right, with Fofana finding Fernandez. Using his first touch, he finds James who gives it straight back to the Argentine. He slips in Joao Felix, but his ball across to Havertz is just too light, affording Coleman the chance to step in at a crucial time.
Their attacking shapes under Potter have really improved in the last few weeks.
Havertz then has an effort which Pickford comfortably gets down to.
16': Chelsea 0-0 Everton
Everton try to press as Chelsea play out but it's disjointed and there's seemingly little organisational patterns to it, which makes the whole concept of pressing redundant.
Koulibaly, playing the middle of Chelsea's back three, toys with Demarai Gray to find Kovacic who drops in, before the Croatian slips it into Badiashile, and just like that Chelsea are in Everton's half.
McNeil has Everton's first effort, when he's afforded time to receive and turn around 30 yards from goal. He sends his shot high into the Shed End. Poor.
14': Chelsea 0-0 Everton
Godfrey wins a free-kick after receiving a push in the back from James. Pickford takes the free-kick and sends it high into the spring sky.
Without Calvert-Lewin or any other target man, however, that is meat and drink for Chelsea's centre-backs and they're allowed time to build again.
Darren England, the referee, is taking charge of his first game at Stamford Bridge. No controversies as yet.
12': Chelsea 0-0 Everton
Everton can't have enjoyed many more than 30 or 40 touches as a collective. Pretty miserable stuff from them so far, you'd have to say.
Fernandez and Kovacic are running things, mainly because they're being allowed so much space in midfield. Doucoure and Onana have to get closer to them.
10': Chelsea 0-0 Everton
Potter will be encouraged by the way Chelsea's players are beginning to combine and find patterns and nice shape to their interplay. Fernandez, Felix and James, arguably their three best players, combine well in a triangle which almost sees the Portuguese slipped in behind but he gets it stuck under his feet.
They come again, and this time Joao Felix does well to take a touch and shift the ball quickly after a nice pass by Kovacic. He's around 14 yards out, and he cannot be afforded the time and space to turn there.
7': Chelsea 0-0 Everton
Everton make a rare foray forward after a long diagonal from Coleman which Gray, to his credit, does well to knock down when pressured by Badiashile.
You can throw as many balls forward as you like, but is Gray really the sort of player who's going to thrive? We will leave that question to linger.
Chelsea respond by launching it forward themselves, bypassing the midfield. Chilwell is almost in down the left but Tarkowski does well to get across and clear for a throw in.
Mr Boehly in attendance
He looks to be vindicated for his insistence on sticking with Potter amid all the noise.
4': Chelsea 0-0 Everton
It's an enticing delivery which Keane does well to head behind for a corner. Everton are already camped deep inside their 18-yard box.
If they want to claim all three points today, you'd have thought they need to keep a clean sheet. Though that's almost extinguished as the ball drops to Kovacic on the edge of the box. He comes onto it brilliantly, but just sends it wide of Pickford's left-hand post.
2': Chelsea 0-0 Everton
Lovely evening in west London. Spring-time football is the best kind of football.
Chelsea have missed James and Chilwell, and they show why. A lovely switch of play from right to left gets the left-back in behind Coleman. His cross is cut out by Tarkowski.
The hosts then come again and win a free-kick after a shove from Keane. Chilwell stands over it.
1': Chelsea 0-0 Everton
Chelsea get the ball forward initially to Joao Felix. He is immediately swarmed by a clutch of Everton players and the visitors win a throw in after it deflects off him.
Coleman launches it up the line. Not the first time Everton get the ball forward airily this afternoon, you'd expect.
Chelsea get us underway
Chelsea, attacking the Matthew Harding Stand in the first period, get us underway.
Players are out
Matter of moments before kick-off.
Lovely moment with Jordan Pickford this week
Dyche on players taking on instruction
'The players have been very adaptive," he said. "They've listened, they've absorbed a lot of what we've offered them, particularly in the first week, 10 days, maybe two weeks because we really tried to cram a lot in then, really sort of force feeding them a lot of what we thought was important.
'People sometimes think, 'Well that's part of their profession' but you've still got to go out and play. You're taking in a lot of information, sometimes new to your style or your game. It is more tricky than people sometimes think, to add in new tactical thinking and different professional standards that we represent.
"As the weeks have gone on they've got more used to what we do and then it's about standards and driving the standards and the consistency of the standards.'
Some big results across the Premier League today.
Leeds have won at Wolves by four goals to two, which is a huge result at the bottom. As soon as one side appears to be pulling away (See: Nottingham Forest and Wolves) from the drop, they are hauled back in.
Tottenham surrendered a two-goal lead to draw 3-3 at Southampton, while Bournemouth were brought back down to earth with a 3-0 beating at Aston Villa.
Leicester came from a goal down to draw 1-1 at Brentford.
One player Everton will have to do without today is Calvert-Lewin, who appears to have again broken down nearing a return. Poor lad, his body just cannot seem to cope at the moment.
Dyche, to his credit, has consistently said since he arrived in January that the most important thing is the striker's fitness and that is what they are looking to improve. They are not putting any pressure on him to return for the crucial relegation scrap.

How much have Chelsea missed Kante?
Quite a lot, it is fair to say.
The France international went off injured against Tottenham at Stamford Bridge in August clutching his hamstring and has not been seen since. They have had to remain very cautious over his return date, but today is that day. It will be interesting to see how many minutes he gets.
'There is a chance for him to be in the squad,' Potter said on Friday. 'It would be the first time so it’s fantastic. Managers before me have spoken very highly of N’Golo because he’s a top, top player.
'He’s been a huge miss to us. That’s not to say the other players haven’t given absolutely everything because they have, but N’Golo Kante is N’Golo Kante. A top player.
'It’s great for us he’s back. We need to be mindful of the fact he’s had a long injury and we need to take the next steps to get him up to speed in the Premier League, which is what we’ll do.'
That's the team news done, time for some preamble.
Both of these sides come into this clash with a renewed sense of optimism that they will strive to use to drive on the remainder of their campaigns.
Chelsea are on a winning run of three games, which only the same number of weeks ago, almost, seemed extremely unlikely. Potter has shaken off questions about his future until at the least the summer with their progress to the quarter-finals of the Champions League, and his plethora of new signings are beginning to acclimatise.
Matched with Kai Havertz's most consistent few weeks in a Chelsea shirt, things are looking up.
Everton, meanwhile, are really looking like a Dyche team. They are not the prettiest watch, but they will not care - survival is all that matters now. Last week's win over Brentford was backs-to-the-wall for much of the afternoon, having taken the lead very early on.
They are running more than they were under Lampard, and they have more bite and resilience. That said, goals are a real issue, and with Dominic Calvert-Lewin yet again facing a spell on the sidelines, that continues to be a major worry.
Everton - unchanged from Brentford
Dyche's team is unchanged from the victory over Brentford last weekend.
Everton: Pickford, Coleman, Keane, Tarkowski, Godfrey, Onana, Doucoure, Gueye, Iwobi, Gray, McNeil.
Subs: Begovic, Holgate, Mina, Mykolenko, Maupay, Davies, Coady, Garner, Simms.
Chelsea - Kante returns
Fresh off the back of three consecutive wins, Potter now has the added bonus of returning players. Their injury problems at the turn of the year are beginning to dissipate.
Kante returns, having last appeared for the Blues in August 2022 - under Thomas Tuchel. How time flies.
Three changes from the side that beat Leicester, with Badiashile, James and Pulisic coming in.
Chelsea: Kepa, James, Fofana, Koulibaly, Badiashile, Chilwell, Kovacic, Enzo, Joao Felix, Pulisic, Havertz.
Subs: Bettinelli, Kante, Loftus-Cheek, Chalobah, Mudryk, Gallagher, Chukwuemeka, Madueke, Cucurella.
Hello and welcome
Good afternoon and welcome to Sportsmail's live coverage of Chelsea's clash with Everton at Stamford Bridge.
Team news to come imminently.
