Speaking in Saudi Arabia, Roger Federer's coach Ivan Ljubicic was asked how much time the Swiss has left in the professional tennis. "I don't know how long Roger will be on the tour. That is a question for him. I'm just happy to have him so motivated.
He just loves playing tennis. Tennis is our life", said the Croat. On Djokovic's, Nadal's and Federer's dominance, Ljubicic concluded: "I still see the big three on top. They are the best players in the world.
They will always be the best players in the world. But the only question is if they can play enough, to stay there. It's hard to imagine that somebody can play better than all three for a whole year."
