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

What distinguishes tennis is respect for one's opponent, one's conduct on the court.

When one player is better than you, at this moment, the only thing you can do is work, try to find solutions and try to wait a little bit for your time. I'm going to wait and I'm going to try a sixth time. And if the sixth doesn't happen, a seventh. It's going to be like this. That's the spirit of sport.

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.

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

I don't think about how going to be the match. I think about try to do the right things to win. I don't think about how easy can say or how tough can say. I go on court. I try my best.

For sure, with golf it's not a physically demanding sport like tennis. That's what makes tennis great - you combine both things. It's a very mental sport and at the same time can be dramatically physical. But I do admire the mentality of sport more than the physicality because physical performance is much easier to practice than mental performance.
