Too bad he's such a headcase that the slightest adversity and he's ready to start punching people.
Look at what a fuzz people made about Tevez. Or that Vucinic was a lazy gipsy, etc.
What they needed, was a coach with balls the size of jupiter. And look how it evolved. Vucinic was a keyplayer in 2 scudetto's and tevez is storming the league, beeing our best player for weeks now.
Balotelli, has the big problem that he never had a coach after Mourinho, that could do this. Mancini, Allegri, Seedorf, all a bunch of twads not really know to keep a tight leech and be great people motivators.
Just look at Pogba.Such an attention drawer. Could easely have went much less well at any other club. But conte kept him tight, deciplinned him when neccecary, molded him into the starmidfielder he's becomming
He could do the same with Balotelli. Mario is also just some attentiondrawer with insane talent. But he needs a master to put him on a leech, and cut the impurities.
