I admire a lot of people, but in terms of sport I've always loved the mentality of Tiger Woods on a golf course. I always love his eyes when he's setting himself and focusing on his decision; he has a really strong, focused face and believes that he can make the shot.

What distinguishes tennis is respect for one's opponent, one's conduct on the court.

I take pleasure in tennis and the hope that it requires.

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

I think is about confidence. Is about doing the right things. Is about being healthy. Is not about if I want to work or if I don't want to work. Is about if I can work or if I can't work.

It's more a tennis problem than a mental problem. The transition is difficult. It depends how much time you have. Playing on grass can sometimes be a bit of a lottery.
