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.

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

Maybe if you're playing in London or America, you don't feel that pressure quite as much.

Tennis players go into a press conference, and almost every one of them is the same. We do very little differently on a day-to-day basis.

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.

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.

When I was a kid in Adelaide, I dreamed of becoming No. 1 in the world, winning a grand slam and the Davis Cup for Australia.
