Wait are you retarded or what? Didnt you just post manga page showing Minato doing a combined tbb with Naruto? You know how a combined tbb works right? Both parties focus their chakra at one point to create the tbb. It can't be done if one party can't perform a tbb.
As for those saying Naruto had to train for tbb, I'd like to remind you that unlike Naruto, who simply learnt rasengan from Jiraiya, Minato created it, by studying tbb for years. The only reason he couldnt use tbb when alive was because he didnt have biju chakra.
