A lot of times I had some problems, but I always had the passion and the personal motivation to keep going, to keep working hard, keep fighting for the things that really motivates me. That's all.

I don't have any idols, any heroes, nothing, no.

I always work with a goal - and the goal is to improve as a player and a person. That, finally, is the most important thing of all.

Today people hit the ball with much more strength. Almost every player is capable of playing a winning stroke from any position. This means the balls arrive more quickly. If you want to reach them, you have to slow down from a high speed or suddenly change direction. These are moments when you can injure yourself, and that's what wears us out.

I only ever run when there's some point to it - say, if it's in a game of tennis.

My uncle developed the training philosophy. His idea of good tennis training is basically quite simple: you must try to gain time.

I'll never have a tattoo - I just don't like them, and when you're old they can look a disaster. As for piercings, I don't like them on men.
