There are many moments during a match when you are tense, wrestling with yourself. Tennis is a lesson in self-control.

It's the same old story, all you think about is money.

I am afraid of a lot of things. A dog. I could be afraid of a dog that's upset, for example. And on the tennis courts, maybe on the outside I look fearless, but on the inside, I'm scared. There's not one player in the world who isn't nervous before matches. Especially important matches.

Hard courts are very negative for the body. I know the sport is a business and creating these courts is easier than clay or grass, but I am 100 per cent sure it is wrong.

Most important thing, I am not a player who win the serves because I serve aces or free points, no. When I winning a lot of serves is because I am playing well from the baseline. That's why.

Win 10 times in an important event like Monte-Carlo is something difficult to describe the feeling. Every year have been a different feeling. At the same time is always a unique moment every time I have this trophy with me.

Tennis is beautiful when you can see tactics, when players don't just react but are able to act and think.
