What is the Laver Cup and who else is playing?published at 19:03 British Summer Time 23 September 2022
Europe take on a world team in the three-day Laver Cup, an annual event which started in 2017.
As well as Federer, Nadal and Murray, 21-time Grand Slam winner Novak Djokovic is also on Team Europe, who are captained by Bjorn Bjorg.
Team World is captained by John McEnroe - Borg's arch rival in their playing days - with American Taylor Fritz and Canadian Felix Auger-Aliassime also among the squad.
The Laver Cup, named after Australian great Rod Laver, was Federer's brainchild and Europe have won all four previous editions of the event which sees a total of 10 singles and two doubles matches.
Each match win is worth one point on Friday, two points on Saturday, and three points on Sunday, with the first team to earn 13 points declared the winners.
The event is sanctioned by the ATP but does not carry ranking points for the players. Three players on each side are determined by the world rankings, with three others picked by the captain.
