It's the same old story, all you think about is money.

Is only a tennis match. At the end, that's life. There is much more important things.

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.

You have to accept both losing and winning well. I've stayed calm when I'm winning and I've stayed calm when I've lost.

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.

It is no longer enough to play very well. You need to be able to give an answer at all times and everywhere. You cannot hide. This has something to do with maturity, and that is something you only acquire over the years.
