He'll go down as one of the guys who changed our sport in a lot of ways, not only the way he played the game, but also the way that he conducted himself on and off the court.

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.

Maybe I have to work a bit harder on clay. It's a challenge and I've always liked challenges. Whether I will ever win the French and master playing on clay, who knows? But I'll give it a shot.

I'm not a guy who needs to read motivation books.

He's up there. But (Marat) Safin, on his game, is as hard to beat.

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

I'm an outside chance at Roland Garros but my focus is really on Wimbledon where it is realistically between me and Roger Federer to win.
