The 20-time grand slam champion will play a doubles event on Friday in London, which will mark his last competitive tennis match.
Rafa Nadal, Novak Djokovic and Andy Murray will join Federer on Team Europe.
And fans got a glimpse of the enormity of this edition of the Laver Cup when Djokovic arrived at the O2 Arena and greeted Federer.
The 41-year-old visited Djokovic during a practice session, which also saw him see British rival Andy Murray.
The tournament is hitting tennis fans with a sense of nostalgia having watched the 'Big Four' take the game to new heights.
Not since 2019 have Federer, Nadal, Djokovic and Murray competed at a tournament and this will also mark the last occasion.
WTA World No.1 and US Open champ Iga Swiatek was quick to praise the amazing scenes at the Laver Cup.
