When I was 4 my mother got divorced and we were very close to each other. I always wanted to be with her. She took me everywhere. When she went for dinner with friends or when they had meetings at the tennis club, I was always there.

I did things I should not have done. But people make mistakes, especially at my age, when you feel you are so smart, but in fact you are an asshole.

Sometimes I wouldn't give an interview because I didn't have the time or something else was more important. So they come up with a story which I don't think is always true, but they have to sell papers.

I've never had big problems about being long on the court. During the U.S. Open I played three events (singles, doubles, mixed doubles) and some people asked me if I want to stay overnight on the court.

I always give Lindsay so much credit for her tennis game, for her attitude, for her person, and because of how she deals with all the things. I don't think people give her enough credit for how well she's doing.

The game overall has gotten so much better, stronger, more physical parts to the game.

No, because I think I have a reason to believe in myself and I think I'm also pretty confident about who I am and what I'm doing and it might be because I'm still at the top too.
