In order to stay where I am - and I want to do that - I have to stay dedicated as well as I have been before I became No. 1.

I haven't been in tennis for that long, but what I can say is that we have a lot of young guys at the top who are willing to do a lot of good things for tennis in general.

Mangling my racket and an odd swearword on the court is not something I am proud of and it shouldn't happen, but even my coaches have told me that it's sometimes better to let it all out, the anger inside you, because keeping it bottled would just eat you up in the long term.

Pressure is part of what we do. It's always present.

Not everybody can like what I do, and if you feel that somebody is coming up closer to you and starting the rivalry and everything, you maybe change your position to him.

In my case, I can sincerely say nothing is impossible.

Nobody actually played tennis in my family.
