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.

I've always played well in Sydney. Hopefully, I can get some matches there under my belt before going into Melbourne.

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.

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'd like to think there's lot bigger matches, you know, around the corner for me.

I still feel it out there. It's just when I jam my foot off during matches. It's something you can't test before a match. So I'm just trying to build it up.
