That's painful always to lose.

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

If you want to belong to the best, you need good technique and, perhaps even more importantly, a good eye. If you see the ball sooner, you have more time to think about how and where to return it.

I just try to win the match by fighting for every point, and running down every ball.

My serve can get better, for sure. It's not just about serving bombs, but positioning, variation in speed, in spin.

Something that works for one person could be a disadvantage to another.

Playing well or playing bad, I have to play aggressive. I must play aggressive.
