I learned during all my career to enjoy suffering.

Even if I have already peaked, I have to believe I can improve. I wake up every morning, and go to practice, with the illusion that I'm going to get better that day.

Is always the motivation to play better and better. But I think we are in a very good way to keep winning matches. That's most important thing for me.

Certainly I would like to have some of the qualities of other players and obviously from Roger Federer. But believe me, there are plenty of other abilities that are important, particularly mindset and strength.

I play each point like my life depends on it.

I like a lot of sports. Especially football - it's my favourite sport. My uncle played football in Barcelona for nine years and played for Spain in three World Cups.

I am No. 8 in the world. I am not No. 100.
