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.

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

The older you get, the more you learn.

I find this accusation so horrendous, so monstrous, that I have decided to confront it head-on by talking to the press. I am frustrated and angry. I believe that I am absolutely, 100 per cent innocent. I assure you: I have never taken drugs.

I've lived for 10 years in Switzerland, so I speak German.

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

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.
