yeah about thatLel,I don't get why some people are acting as if it is the end of the world.It is not like Naruto is hopeless against Sasuke just because Sasuke is faster than him.Naruto can do just fine against him and it seems like they are fully aware of eachothers abilities.Notice that Sasuke is analyzing the battle and asking Naruto to use appropriate jutsu's and no need to mention about Naruto asking Sasuke to stop Madara.It is exactly as if Naruto clearly knew that Sasuke can stop him which means that Naruto has knowledge on Sasuke so you have no reason to feel bad about it as they can do just fine against eachother.
