Federer missed last year's event due to the knee injury that has kept him out since Wimbledon last year. This will be his fourth time representing Team Europe at the Laver Cup, where he owns a 6-0 singles record and a 2-3 doubles record.

Team Europe consists of the 'Big Four' of Federer, Novak Djokovic, Rafael Nadal and Andy Murray as well as Tsitsipas and World No. 2 Casper Ruud, who reached the final at Roland Garros and the US Open this year.

Trying to end Team Europe's reign as Laver Cup champions will be Team World's Felix Auger-Aliassime, Taylor Fritz, Diego Schwartzman, Alex de Minaur, Frances Tiafoe and Jack Sock. Play begins on Friday.
