Roger [Federer], he brought tennis... one level higher. Normally he toys with everybody. With all respect to other players, he does whatever he wants on the court against them. It's incredible what kind of game he can play.

If I was the type of person who had tennis, tennis, tennis all the time and I went to bed and ended up dreaming about tennis, I would go nuts.

I've lived my life the way I wanted to, whether scaling the mountains, partying long into the night or having fun playing soccer.

I'm not a materialistic person.

You can find flaws in Agassi and Sampras, but Federer has none.

My mother said I would have more chances to become a tennis player than a football player.

You have to wake up and you have to run if you want to survive.
