I doubt about myself. I think doubts are good in life. The people who don't have doubts I think only two things-arrogance or not intelligence.

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.

I will do as I usually do. Tomorrow is going to be a day like any other day.

Don't think about being the number one in the world, try instead to get through today's program as well as you can. Then we will see whether one day you'll end up as number one or number 100.

I think I am a complete player. I can play well on all the surfaces. For me, the clay might be easiest, but I am not a specialist on clay.

I have always tried to avoid regrets. Could I have done differently some things in my career? Maybe.

It's hard to say, 'I don't believe in God.' I would love to know if God exists. But it's a very difficult thing for me to believe.
