I've stayed calm when I'm winning and I've stayed calm when I've lost. Tennis is a sport where we have a lot of tournaments every week, so you can't celebrate a lot when you have big victories, and you cannot get too down when you're losing, as in a few days you'll be in the next tournament and you'll have to be ready with that.

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.

There is some moments on the career of everyone that are important ones. Is obvious that first title on clay makes a big difference. After that, I was confident enough to keep going, winning in Barcelona, in Rome, then in Roland Garros.

I was shy when I was a kid, I was very shy, but now I think I've improved a lot. I can speak OK with the media and with the people. My English is still bad but I feel a little bit better now than before.

When one gets beaten by somebody better, one has to know how to lose with humility. Sure, I could have served better. Sure, I could have hit my forehand harder. But the truth was this was like an avalanche, and there was no way to stop it.

However great your dedication, you never win anything on your own

I don't have any idols, any heroes, nothing, no.
