Wimbledon & US Open, Federer did not play a convincing game.

Davy won't be too amateur. If Nadal were not injured and Novak did not have strong wind behind him at those set points, his ball wouldn't have been too long by 1~2 mm.

If Federer keeps on winning like today, there will be more and more people will not agree that he is the best player ever, even he can win 20 Grand Slams.

The best player will have to convince most people that he is superior to other historical ones, but search for how many tennis fans still think that his nowdays opponents are too weak and he is little bit lucky? These tennis fans are not always so amateur as you may think, even I could be so amateur.
