My greatest point is my persistence. I never give up in a match.

I'm amazed that years after I stopped playing tennis, people still recognize me in restaurants and ask for my autograph.

When I retired from tennis I wanted to do other things with my life.

On Rafael Nadal: Every point he plays is like match point. That's why he's the champion right now.

I have a great family, great kids. I have practically everything, you know? Sometimes I have to pinch myself. It's really true: Life starts at 50.

I just hated to lose.

It has changed, quite a lot. It is very different now, there are quicker men, they are taller, stronger, have great stamina. The balls have also become faster. Tennis has now become a power sport. There is more depth in the game, as well, there are many more players than there used to be. The entire character of the game has changed.
