I am number one in the world, so I have the right to be arrogant

I've always said I'm a good horse but I'm still an underdog.

One day you can be a kid, but another day you have to be like this is your job, you play tennis. You have to work for that.

The top players talk more now, and we have more meetings. We're just trying to get things better. But we still need somebody who could make a difference.

A lot of these young girls, they dont even know what the game is about. They have never seen a drop shot, a slice and all the mixture and variety I have.

The game overall has gotten so much better, stronger, more physical parts to the game.

I've lived for 10 years in Switzerland, so I speak German.
