I play tennis five hours a week, from Monday to Friday, for one hour every day. I like to be fit. If I can't exercise, I feel bad - I need to sweat and run to feel like I'm in good shape.

Basically I started playing double handed on both my forehand and backhand side because my first racket was very heavy.

If you're afraid of losing, then you daren't win.

I just hated to lose.

Tennis is a traditional game. A big sport like tennis does not need too many changes. The game has become too fast, there are hardly any long, interesting rallies these days. So maybe slowing down the courts could help. But you can't really stop a sport from evolving.

My greatest point is my persistence. I never give up in a match.

On Rafael Nadal: Every point he plays is like match point. That's why he's the champion right now.
