What rivalry? I win all the matches.

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.

The top players talk more now, and we have more meetings. We're just trying to get things better. But we still need somebody who could make a difference.

Any tournament you go to, you want to win it.

I grew up on the tennis court with lots of other kids. There were like 40 kids all afternoon and I was one of the youngest ones, so I always had to chase everybody to keep up.

I've always said I'm a good horse but I'm still an underdog.

I still speak Czech with my parents because I was born there.
