I played almost four hours today, ... Im very, very tired.

Tennis is beautiful when you can see tactics, when players don't just react but are able to act and think.

I have the same bedroom I've always had. It's clean and tidy when I get home, and after two or three days it gets messy and my mother nags me.

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.

The glory is being happy. The glory is not winning here or winning there. The glory is enjoying practicing, enjoy every day, enjoying to work hard, trying to be a better player than before.

The young athletes are supposed to mature, to improve their personality.

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