Nonsense.Madara already implied he went head to head with the Nine tails with his perfect Susanoo.And not the lesser nine tails within naruto, but the ying and yang chakra nine tails.Furthermore, I hate stupid naruto fanboys who believe that naruto can jump from one mode to another in the blink of an eye.If naruto is or get into one of the modes,whether it's sage or Kyubi, he definitely wouldn't have time to change into the other mode during a one on one battle with Madara.Lastly, only a complete moron would think that Naruto would stand even the slightest of chances against Madara when we saw what happen to Naruto clone who was in front of madara when he tried to summon the nine tails.To put it simply, even an Uchiha with a lesser Sharingan (Sasuke before he had MS) can control an or surpress Kurama, so how stupid do you have to be to think that Naruto could take on Madara who mastered his MS.

To put it simply, if you think Naruto can beat Madara you are a f**king moron.Madara is the worst possible match up for Naruto, with the second being Hashirama.
