The pair will represent Team Europe against Team World's Jack Sock and Frances Tiafoe at London's O2 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.

"I have had some tougher moments as well in the past, being horribly nervous all these years sometimes before matches. This one definitely feels a whole lot different.

"Of course, it's super special playing with Rafa. I'm happy to have him on my team and not playing against him."

US Open semi-finalist Tiafoe, 24, says it will be "a special night" playing against Federer in the final match of his career, according to BBC 

"I'm just excited to play two up-and-comers," laughed the American.

"The crowd is obviously going to be for them. You understand that kind of moment, and just go out there and do your part and just try to get a win."

Team World captain John McEnroe said all of his team wanted to play against Federer, joking he needed to "flip some coins" to make his picks.

"[Jack and Frances] are opponents to a very unique situation that we are all fortunate enough to be around. This is like an incredible moment for our sport," said the seven-time major singles champion.

"The good news is that if they win, they are not going to be villains. This is about the celebration of what Roger has accomplished and him ending it and hopefully not hurting himself, is what I'm thinking."
