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

Basically I started playing double handed on both my forehand and backhand side because my first racket was very heavy.

Tennis is a traditional game. A big sport like tennis does not need too many changes. The game has become too fast, there are hardly any long, interesting rallies these days. So maybe slowing down the courts could help. But you can't really stop a sport from evolving.

Roger Federer is stylish.

I wanted to win, even in practice.

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.

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.
