I definitely want to get out of tennis and try something completely different.

It's a completely different situation right now because last year it was the time that nobody expected anything from me anything -- I had nothing to lose, basically I was starting from zero. And now I'm back in Top 5. And for me it's a different stage.

Many say that (Pete) Sampras is the greatest player. But I say with all due respect to the rest, that he (Roger Federer) is the most complete player in the world so far.

If I was the type of person who had tennis, tennis, tennis all the time and I went to bed and ended up dreaming about tennis, I would go nuts.

I think it's difficult to be No. 1. 'There's too much attention, too much expectation from other people.

But when I'm losing a few matches, suddenly 'It's his fault', 'He doesn't want to practice', 'He doesn't need it', 'He doesn't care'. And when everything goes well, there are people coming behind the stone, saying, 'Oh, my God, he's back finally, and I was there to help him out'.

One of the most important things, actually, when you're playing on grass, is to move.
