The issue with Pogba has more to do with where he can go, versus where he currently is. If he was this prodigious talent playing for a lower level club, then his ceiling, and therefore opportunities, are much higher.
He is currently at arguably one of the top 5 clubs in the world. Where else can he possibly go? Bayern, Madrid, Barcelona? He is another cog in the machine at those clubs. Are there any clubs in England or France who are better than us? I think not. It's not as if he has 20-25 options out there for him where his lot in life could be better than where he is now.
And that is not his fault. It has more to do with the quality of Juventus than anything else. And yes, I know that those three clubs are currently on higher rungs on the ladder than us, I get that. But again, no matter where he goes, his chance of being THE STAR on the team, if that is what he wants, if he wants to be the leader, are really limited. Unless he takes a step down, and there is no way he would do that.
