why would itachi say that madara tamed the kyubbi if he tamed him himself? It doesn't make any relavant sense. If he indeed did tame the kyubbi he would've told so to Sasuke. NOT give it as an achievement of another person.
neither did he say he can do it. But seeing as madara was the one who learned how to do it and who passed it to obito it should be more unlikely that he knew. But of course neither of us can prove it to the other with this much limited information. Let us agree that sasuke wins this fight.
Either way, he meant you can't attempt to control the kyubbi without MS. similiar to how you can't attempt to perform kamui using 3 tomoe. While as neither madara, sasuke or itachi can perform kamui even though they all have ms and above. Simple really. Another proof is that madara was the first one to tame the kyubbi where there wre several other mangekyou users other than himself. As i said again, having ms doesn't guarantee the ability of controlling a tailed beast.
Well, it wasnt acutally Itachi, but... ->
where exactly was this fact stated?? Just because two people could use it using MS doesn't make every individual able to. Amaterasu was said to be technique specific to MS but obito can't perform it. Unless done, none other than madara and obito can control kyubbi.
