No, I'm not (disappointed). There's no reason to be because I'm on an incredible run. You always expect a loss once in a while. So when it happens, why be disappointed if I win over 90% of my matches.

What I think I've been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.

But so far I have the feeling that the chances are there to repeat last year's season.

Hopefully I can just have another terrible year with only the one Grand Slam and that will be just fine.

I enjoyed the position I was in as a tennis player. I was to blame when I lost. I was to blame when I won. And I really like that, because I played soccer a lot too, and I couldn't stand it when I had to blame it on the goalkeeper.

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.

I always knew I had something special.
