People can take this for what its worth, but I can guarantee what happened to Rafa after Wimbledon last year (not making a final and losing in every tournament) will not happen again this year. I'm sure he learned from that experience....
Thats not to say that Federer isn't #1 anymore, but people are making too big a deal out of Federer being far superior than Nadal....its not true, you just have to give it time to see. Comparing people that are 6 years apart, you can't really. In fact....
At the same age, Federer was just winning his first masters shield in Hamburg, and had 0 slams. Nadal just won his 8th shield folks, and is in line to win more over the next 2 weeks, and his 3rd slam possibly by age 21?
Of course the haters will say that they are 2 different styles of games, and that Nadal will burnout. But Nadal, even being injured and already having slumping parts of his season, still continues to turn it out at times. He has 2 shields this year (2 different surfaces) while Federer has 0, but does have a slam.
You just can't compare yet folks
Note - Nadal is already 4th on the all time list of Masters Series Shield winners, with Agassi at 17, Federer at 12, and Sampras at 11. Just think about it for a second folks (Oh, and 3 of his have been on hard courts!)
