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.

I feel like when I'm match tough and match hard and played a lot of matches I got that competitive winning spirit going and I can get on some rolls like I did last year. I won San Jose, Indian Wells and made the semifinals in Miami so it can happen for me.

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

Ten minutes? That's the women. It's not for the men; not for the real game, mate.

(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.

Everyone has to call 'time' at some stage.
