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.

When you're good at something, make that everything

I love tennis! I've always felt like this because it is such a classy sport with a great, competitive flair to it.

The serve, I was too young and too small and... not enough powerful to have a good serve when I was young, so my forehand was always my signature shot. So I used to always run around my backhand, you know, use my forehand as much as I could, and so that's why I think it's my strength also today, you know.

Seriously. I'm not playing to prove anything to journalists. I'm playing for myself, for my fans,to make people happy.

I can't stay No. 1 for fifty years, you know. We'll see what happens.

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.
