Tennis is a hard sport. There is a lot of competition all year and you play alone.

I am a guy who likes to do what I am doing with passion, whether it's a soccer match with friends or golf.

Some people may learn something from the way I play tennis. But there are also players who are better than me in certain techniques.

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.

I am No. 8 in the world. I am not No. 100.

Always I believe that I can play better. But I am happy.
