You know growing up in Sweden meant we had a lot of rain when we played tennis. We were taught on clay courts but because of the weather, we had to go indoors a lot.

You never know how long Federer is going to play, but in my opinion he has at least one or two more grand slams to win. It depends how long he stays motivated. For me, he is the greatest player to ever play the game.

It's not easy to part with the trophies. However, I do need to have some long-term financial security for those close to me.

You have to find it. No one else can find it for you.

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.

My greatest point is my persistence. I never give up in a match. However down I am, I fight until the last ball. My list of matches shows that I have turned a great many so-called irretrievable defeats into victories.
