Why'd you leave the match, huh?

(Andy Roddick's) a different kind of guy. I don't spend a lot of time with him. His coach in the past (Tarik Benhabiles), I didn't have a lot of time for at all. He was a bigger problem than Andy.

I was lucky enough to win the Davis Cup in my first year in 1999. I won my first slam at the U.S. Open in 2001 and became world No. 1 later that year. By the age of 20, I'd done it all.

I was actually really happy with where my game was at. That's probably the most disappointing aspect.

I liked Pat Cash, and I loved Mats Wilander. I went to the Australian Open with my parents, and I used to watch Wilander being cheered on by the Swedish fans, and with his game style being like mine, I drew comparisons with him.

That's when you've got to grit your teeth and hang in there and try and find a way to win when you're not playing your best tennis - that's what I can be proud of

When I go out to play, I still believe I'm as good as anyone out there. I don't have to prove anyone wrong. I know what I've done and how well I can play.
