Roger Federer and Tomas Berdych have been getting set for the Laver Cup in Prague, ahead of the tournament which will take place in September in the city.
Honouring the legendary Rod Laver, the team-format competition, which will see the best six European players take on six stars from the rest of the world, is set for lift off later this year.
And, get this - Bjorn Bjorg will captain Europe while John McEnroe will do the same for the opponents.
Who better than Federer to help promote the event in honour of one of his idols!
