You can find flaws in Agassi and Sampras, but Federer has none.

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'.

The Olympics is not for tennis and tennis does not need the Olympics. It is not my goal in life to win a gold medal.

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

Roger [Federer], he brought tennis... one level higher. Normally he toys with everybody. With all respect to other players, he does whatever he wants on the court against them. It's incredible what kind of game he can play.

Right now my main aim is not to get injured any more. I am a little bit afraid of running and sliding because the ankle was so painful. But I am not a person who runs a lot, who spends a lot of energy on the court. If I am mentally OK, if nothing is bothering me and I want to play, then it is fine.

Wimbledon is not the tournament I love. I don't like how they treat the players. There are small things that don't cost them anything and they make such a big deal out of it. If they treat us this way, well, we have to treat them the same. We want to be respected, the way we respect Wimbledon, even if it is not the best Grand Slam on earth.
