There is some moments on the career of everyone that are important ones. Is obvious that first title on clay makes a big difference. After that, I was confident enough to keep going, winning in Barcelona, in Rome, then in Roland Garros.

I was passionate about soccer. I still am. Odd, though - playing soccer always made me much more anxious than playing tennis. On soccer days, I'd be out of bed by 6 in the morning, all nervous. But I was always calm when it was time for a tennis match. I still don't know why.

When one player is better than you, at this moment, the only thing you can do is work, try to find solutions and try to wait a little bit for your time. I'm going to wait and I'm going to try a sixth time. And if the sixth doesn't happen, a seventh. It's going to be like this. That's the spirit of sport.

I am a guy who likes to do what I am doing with passion, whether it's a soccer match with friends or golf.

The young athletes are supposed to mature, to improve their personality.

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.

I always had the theory that the most important thing is be happy, enjoy what are you doing, and be fresh mentally.
