Anyone in hand-to-hand will easily lose to Naruto. That much was pretty much established when he fought Pain. Naruto pulled off that broke-ass more + bigger rasengan attack even without the Kyubi's chakra. I imagine now he'll be able to create a rasengan the size of a planet.

In any case, I still feel the same way about this fight as I have for 90% of Naruto's fights. And that is that if Kishimoto wants Naruto to win, Naruto will land a rasengan. If Kishimoto wants Naruto to lose, Naruto will miss with his rasengan. Its ridiculous to make intelligent assumptions about matchups, as it doesn't even seem like Kishimoto knows what all the characters are capable of until he writes himself into a corner.
