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

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.

Even when I was No. 1 in the world, I was taking it one match at a time. I never was a player to look too far ahead, the way draws can pan out.

I have sometimes played my best Davis Cup matches away from home when you stay in the moment a bit more. But it is tough when half the crowd are spitting on you.

Grand Slams are funny things. You have to try to find a way to get through the first week and put yourself in a position in the second week. A lot of strange things happen.

Matches are won and lost so many times in the locker room.

I'm fortunate: I can play as long as I want to play. There's no coach or trainer who is going to say to me that I'm dropped or sacked, it's time to move on. I can play as long as I want to play.
