I've had good times and bad times. That's me. That's how I am.

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.

I've had good times and bad times. That's me. That's how I am.

It's frustrating when you want to play but can't. I didn't touch a racket for three weeks and when I started playing again last week, I still felt some pain in my wrist.

You know why I want to win? Because of 15,000 reasons inside of the tennis court.

It is very hard for me to switch from clay to grass.

I achieved what I want to achieve and I want to continue doing something else.
