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 feel a quarter Indian.

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.

The older you get, the more you learn.

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 still think I have the speed and the variations also to win the matches, but its very good competition and also a great challenge for me too.

I am number one in the world, so I have the right to be arrogant
