I want to be a hero, a small and good kind of hero, even though I know heroes have very short lives.

When you are thrown onto the stage at 17 in such an enormous way, it becomes living on the edge because every step you take, every word you speak, every action you do becomes headline news. And it became, for me, life or death.

Thats the hard part about sport: as men we havent started to be in our prime, but as athletes we are old people. I needed support. I lost trust and did stupid things.

Its silly to say it about a tennis player, but Im an unbelievable hero in Germany. And Germany needs heroes more than any place.

I go to London, my favourite city in the world, and I feel at home.

I believe that everything in life happens for a reason.

We have a guy from Switzerland who is just playing the game in a way I haven't seen anyone - and I mean anyone - play before. How fortunate we are to be able to see that. If he stays healthy and motivated - and the wonderful feel he has stays with him - he is the kind of guy who can overtake the greatest.
