If you want to be a tennis player, then mould yourself on Roger Federer. I won three Wimbledon titles and I wish I could play like him.

I want to be remembered as a great player, but I guess it will be as a player who got angry on a tennis court.

You can tell when someone has been on steroids A guy bulks up, has a new body and never gets tired...You see these guys or girls who come onto the tour talking about their new training programs and their diets where they eat this or that new thingbut they'll never tell you about the drugs they took.

Equipment's the biggest change. And the guys have been getting bigger, stronger, more athletic - so the game has become more of a track meet instead of a tennis match, in a sense.

As they say in sports, the older you get, the better you used to be.

If, in a few months, I'm only number 8 or number 10 in the world, I'll have to look at what off-the-court work I can do. I will need to do something if I want to be number 1.

The good part of having six kids is, there's always one who wants to hug you and say, 'Daddy, I love you.'
