Re: Naruto wasn't talking about "not being able to beat sasuke"
Naruto could be meaning both physically and mentally that Sasuke could not be beaten. Though at that exact moment Sasuke was nearly blind and Naruto was 100%. Naruto could not win in the sense of saving his friend as much as rid the planet of another criminal. But, also with Madara there too trying to fight Sasuke would've been difficult since Madara has yet to be even slightly harmed intentionally, not counting Deidara of course.
