the chidori vs rasengan impacted and it became a draw how can you say that naruto doesnt need kyubi's chakra to beat sasukes chidori when the answer has already been displayed...
I think if the rasengan was fully mastered by Naruto, the outcome probably would have been different. After the draw Sasuke clearly says that was his fully powered chidori, and he also mastered it. In a direct impact, a fully mastered rasengan vs a fully mastered chidori, the rasengan should be able to win.
