My aim over the next few months is that I have a lot of points to defend in Miami and Hamburg, after that I can set my sights on No. 1.

The nicer the point, the more -- the better I feel, the more excited I get. But I never play that my opponent looks stupid. I think that is wrong. I have too much respect for every opponent I play.

I went to Phuket already, but would love to go to Chiang Mai one day.

I am a very positive thinker, and I think that is what helps me the most in difficult moments.

I'm as patient a father as I am on the tennis court. It takes a lot for me to get really upset, but sometimes kids can get you really cross if they really keep bugging you.

It is always in my mind still that I can crush anybody. That's not an issue. But I think that is the same for most athletes. If you don't believe you can win tournaments anymore, then you can't do it.

I'm shocked every time that I've reached so many finals or won against so many players or whatever record it is. It strikes me and makes me obviously very happy and very proud that I've been able to do it for so many years at the highest of levels.
