Sasuke could not beat Gaara but Naruto did. Sasuke had the Chidori but then Naruto learned the Rasengan. Did you see how shocked Sasuke was after the rooftop fight, how much more damage the Rasengan did? When Sasuke had the Curse Mark form Naruto went One-tail. Naruto hit Sasuke's Head protecter instead of landing a fatal blow. We know that either the fight would have been a draw or that Sasuke would be dead. The Shippuden Naruto had learned all sorts of combo's with the Rasengan and improved his control over the Kyuubi. He was able to go two-tails with out losing complete control. Now Sasuke may have the Ems, but Naruto has Sage Mode and Kyuubi mode. Since the fight with Gaara Naruto has found a way to surpass him.PROOF? Please tell me how.
