I still have this image: I can't be controversial, I can't say things.

Losses are always a relief. They take a burden off me, make me feel more normal. If I win several tournaments in a row I get so confident I'm in a cloud. If I lose I go back to the dressing room and I'm no better nor worse than anyone else. A loss gets me eager again.

When I play, I'm boiling inside. I just try not to show it because it's a lack of composure, and if you give in to your emotions after one loss, you're liable to have three or four in a row.

If you're a champion, you have to have it in your heart.

Of all my achievements in tennis, I'm probably as proud of my record on clay courts as any of my Wimbledon, U.S. Open or French singles titles.

My first U.S. Open I think was just very special for me because that was sort of the beginning of what was a 'Cinderella' story for me.

Ninety percent of my game is mental. It's my concentration that has gotten me this far. I won't even call a friend on the day of a match. I'm scared of disrupting my concentration. I don't allow any competition with tennis.
