However great your dedication, you never win anything on your own

There are many moments during a match when you are tense, wrestling with yourself. Tennis is a lesson in self-control.

I was shy when I was a kid, I was very shy, but now I think I've improved a lot. I can speak OK with the media and with the people. My English is still bad but I feel a little bit better now than before.

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.

I'm not the best player in the history of tennis. I think I'm amongst the best. That's true. That's enough for me.

I used to wear sleeveless T-shirts all the time on court, but now I've got a brand new look - I've moved on to polo shirts. Sleeveless T-shirts give you real freedom of movement and they keep you cooler in matches, but I just thought it was time for a change.

If the girls and boys have talent and feel like working on themselves, they can become champions.
