"You have to put him as the best player in the world. Level wise, it is very difficult to say if it is Pete Sampras or Rod Laver. They won a lot of majors. Or Bjorn Borg, for that matter. But if you talk about the level that Pete Sampras played at, I would have to say that, when he played well there was no way Roger Federer would have beaten him. Not yet!"
-- Mats Wilander on Pete Sampras.

It's one-on-one out there, man.  There ain't no hiding.  I can't pass the ball.  ~Pete Sampras

The difference of great players is at a certain point in a match they raise their level of play and maintain it. Lesser players play great for a set, but then less. ~ Pete Sampras
