okay madara uchiha (not edo) is still way more than naruto could hope to be ready for.
think back to when sasuke supressed the 9tails chakra at the beginning of shippuden.
madara controlled the 9tails and went to battle with it. naruto's sage mode isnt going to break through a complete susanoo and madara is the most powerful uchiha... everytime he fights sasuke he struggles, you really think madara would have to worry? he fought hashirama, a man with immense chakra (like naruto) could heal himself without hand seals (like naruto) used mokuton (unline naruto) and actually has past battle experiences with madara (unlike naruto)
there is a reason madara and hashi were feared... naruto is a strong ninja but he isnt on their level
