I think it's the mark of a great player to be confident in tough situations.

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.

The 1980 Wimbledon final with Borg - that's the one I was most proud of to be part of. It's talked about as one of the best matches people have seen so that certainly elevated me in a lot of different ways, even though I came out second in that one.

We should reach out to people to try to go after the fans the way other sports do. Because we can't just depend on the fact that it is a great game.

I'd like to think I could have and should have won more, but that's not the point. And I was at the point where I was playing great tennis in the mid 80s - the type of tennis people hadn't seen before - and I was very proud of that.

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.

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.
