Everybody is doing the best things possible to still healthy and to play as long as possible.

When you get older, if you are healthy, is not a problem. If you don't have the health, then you go home.

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

It should not be a child's only goal to become the best player in the world. That would be a bad, a harmful attitude.

I'd rather lose an argument than get into a long discussion in order to win it.

The US player Andy Roddick reaches speeds of 220 kilometers per hour when he serves. If I train with him every day, I will later be at an advantage against a player whose service crosses the net at 190 kilometers per hour.

In tennis, because of the way it's scored, I don't think that scoring one point out of luck is ever decisive in winning. But, of course, it depends on the moment.
