Everyone has to call 'time' at some stage.

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.

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.

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 liked Pat Cash, and I loved Mats Wilander. I went to the Australian Open with my parents, and I used to watch Wilander being cheered on by the Swedish fans, and with his game style being like mine, I drew comparisons with him.

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