Federer is number 1 and is number 1 in the world of tennis. You cannot even compare him to Sampras. Sampras may have been good on grass and hard court, but when it comes to total dominance in tennis, Federer is the best and will remain the best. Hats off to Federer for winning the Masters which included some of the best in the world pitted against him and still Federer showing all his class and coming out number one. If Sampras was in his place today, I don't believe he would stand any chance against these guys today.
