For sure, with golf it's not a physically demanding sport like tennis. That's what makes tennis great - you combine both things. It's a very mental sport and at the same time can be dramatically physical. But I do admire the mentality of sport more than the physicality because physical performance is much easier to practice than mental performance.

I am happy with being a tennis player and the choice I took when I was 12. But clearly, if I wouldnt have been a tennis player, I would have loved to be a soccer player. But again, I am happy with the choice I made.

I am afraid of a lot of things. A dog. I could be afraid of a dog that's upset, for example. And on the tennis courts, maybe on the outside I look fearless, but on the inside, I'm scared. There's not one player in the world who isn't nervous before matches. Especially important matches.

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.

Barcelona, the tournament is, for all the Spanish players, an amazing event. I think is one of the top events on tour because is a historic event with a lot of tradition. A lot of years of the tournament, a lot of great players have been playing there. And it's in a real tennis club.

I love the crowds in Miami. I feel that is one of the tournaments where I get more support. That helps me a lot.

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