Roger Federer is stylish.

It has changed, quite a lot. It is very different now, there are quicker men, they are taller, stronger, have great stamina. The balls have also become faster. Tennis has now become a power sport. There is more depth in the game, as well, there are many more players than there used to be. The entire character of the game has changed.

I had a great tennis career. I have no regrets. But to find peace with yourself, and to finally be with your family - I'm probably the happiest guy in the world.

Tennis is a traditional game. A big sport like tennis does not need too many changes. The game has become too fast, there are hardly any long, interesting rallies these days. So maybe slowing down the courts could help. But you can't really stop a sport from evolving.

He [Jimmy Connors] has one weakness. He can never say his opponent played well. That's why it feels good to beat him and that's why other players would rather beat him than any other player.

As tennis players, we work and we sacrifice many things. To lose, that's not a happy thing - I mean sure, I was disappointed. You have to come back strong. But to win the last point in a grand slam tournament, that's the most beautiful and most satisfying feeling you can get as a tennis player. It's worth it.

I play tennis five hours a week, from Monday to Friday, for one hour every day. I like to be fit. If I can't exercise, I feel bad - I need to sweat and run to feel like I'm in good shape.
