I don`t know why, but I love the dog eat dog nature of tennis. It`s real, it`s brutal and there`s no hiding place - it's like a one to one street fight. I love the intensity that comes with knowing you walk off court either a winner or a loser. It`s daunting but very exciting. There is no one to blame except yourself, no one cares who comes second.

Winning is about taking your opponent's heart out and squeezing it until all the blood has come out, even the very last drop. There are no prizes for a funny loser.

Media access to us is more regulated than in golf.

I did it my way, and I have no regrets when I look back on my career that it was just a big focus for me.

I feel much more respected in Europe than I do in the States from the press and from the people. Americans expect me to win every match I play.

There's always one shot that I can rely on when I'm not hitting the ball that well, is my serve.

There is no doubt about how hard it is to stay on top in any sport, but to do it in an individual sport for the majority of your career, it is not easy.
