I became a player who goes to a lot of effort while training, who can rely on his will and his mental strengths.

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.

If somebody says I am better than Roger, I think this person doesn't know anything about tennis.

Losing is not my enemy..fear of losing is my enemy.

I feel that love. I feel that energy. I always felt that energy when I'm playing in New York.

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.

It should not be a child's only goal to become the best player in the world. That would be a bad, a harmful attitude.
