Roger Federer admitted at The Championships on Sunday that he is “ready for the challenge” of potentially needing to beat Rafael Nadal, Andy Murray and Novak Djokovic if he is to retain his Wimbledon title. “I like tough draws,” said Federer, the seven-time champion. “I don't shy away from them. There's no control over it. All you can control as a tennis player is who you play and who you face. I have a very difficult draw with Rafa being in my quarter.
