Federer and Nadal team up for doubles on Friday at Laver Cup

LONDON : Roger Federer will team up with friend and rival Rafa Nadal for Friday's doubles encounter at the Laver Cup in what is expected to be the Swiss great's final professional match.

The 41-year-old Federer will play competitively for the last time at this week's Laver Cup, turning out for Team Europe alongside Nadal, Andy Murray and Novak Djokovic - the three biggest rivals of his glittering 24-year career.

Federer, who has won 20 Grand Slam titles, has struggled with knee injuries in recent years and said last week that he would end his career after the Laver Cup in London.

The order of play released by the organisers for the opening day of the tournament showed Federer and Nadal will play the last match of the evening at London's O2 Arena against the American pair of Jack Sock and Frances Tiafoe.

"I don't know if it's going to happen, but it could obviously be a special moment," Federer said on Wednesday about potentially playing his last match alongside great rival Nadal while also confirming that he was not fit to play singles.
