How quickly people have forgotten. Federer is the only player to win the AO without dropping a set since the establishment of the ATP.
And about the rubbish competition argument, one can argue Nole wouldn't have beaten Safin in 2005, and he would be sitting on 3 AO. If 2005 Federer had Murray instead of Safin, he would have 5 AO by now.
NadalAgassi: I think Serena's final slam tally will be something from 18-27. My best guess is 24 or 25 though; Nole(2010) will never win Wimbledon
