Roger Federer’s final match will see him play alongside old rival Rafael Nadal in the Laver Cup doubles today.
The pair will represent Team Europe against Team World’s Jack Sock and Frances Tiafoe at London’s 02 Arena.
Before that match, Andy Murray will start the evening session in singles against Alex de Minaur at 19:00 BST.
Federer, a 20-time Grand Slam winner, said last week he would retire at the team event, which starts on Friday.
The 41-year-old Swiss said it would be “wonderful” to play alongside Spaniard Nadal, 36, who has 22 major titles.
“I’m not sure if I can handle it all but I’ll try,” said Federer.
“This one feels a whole lot different. I’m happy to have him on my team and not playing against him.”
Federer has struggled with a knee problem and does not feel able to play singles.
