Seriously, I am not a person that I think much about what happened or what didn't happen or what could happen. I happy about the things that happened to me. I'm a lucky person, for sure, for all the things that happened to me during my life.

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.

Everyone is entitled to have their own opinions.

I'm only superstitious on the tennis court.

Today people hit the ball with much more strength. Almost every player is capable of playing a winning stroke from any position. This means the balls arrive more quickly. If you want to reach them, you have to slow down from a high speed or suddenly change direction. These are moments when you can injure yourself, and that's what wears us out.

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.

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.
