I am totally against it. I think it will destroy the game. It will slow it down, lose the momentum and the motion of the game. Who was the genius who came up with this stupid idea? They are looking for solutions on how to save the game and this is not it.

I won't worry about that until I meet him, but there's been no secret formula for anyone up against him on any surface for the last couple of years. But I'd like to get another crack.

I think he had quite bad losses, for example, in the Davis Cup against us...He was supposed to be in the Top 10. I think it's a little bit a pity because he's quite talented guy. But he can be there, but he needs to be more brave, that's for sure.

It will be quite difficult, you have to do something special against him (Federer), he is so far from all of us,

I didn't practice for one month and a half and I played three matches in a row and today I felt really, really tired on the court. I couldn't move properly and I couldn't find my game. My timing was not there. So it's really difficult to play against any player.
