I'm really, really emotional.

All sports are continuously developing, but what they all have in common is that the speed is increasing. That's also true of tennis; the ball is getting faster and faster.

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 normally listen to Spanish music - well, Latin music. I like a lot of singers...

I have no sense of humor about losing

It's hard to say, 'I don't believe in God.' I would love to know if God exists. But it's a very difficult thing for me to believe.

My motivation and aspiration is the same, being number one or being number five. So that's the truth. And my goal is the same - it's to always be happy playing, it's to enjoy the game and improve always.
