- Roger Federer revealed on Monday he wants to join forces in doubles with arch rival Rafael Nadal at the inaugural Laver Cup this year. The Swiss great made the confession at the unveiling of the new tournament scheduled for Prague in September which will pit a Bjorn Borg-captained European team against John McEnroe's rest of the world. Federer, who beat Nadal in the Australian Open final last month, admitted on Monday: "I've always wanted to play with Rafa... just because our rivalry has been so special. "I've seen his wicked forehand go past me too often!" The new addition to the tennis calendar is named after Rod Laver, the last man to achieve the calendar Grand Slam in 1969. "Rod Laver wants us to represent our part of the world with pride and play our best and win for our teammates. We will play to our best possibilities," Federer said.
