Being a good footballer is more than about Goals and assists. Sigurdsson and Eriksen have plenty goals and assists. It is about all the other non recorded elements as well
Given that dominating teams isn't a problem for us, but finishing teams off is, I would say goals and assists is exactly what we need from Pogba. I can think of multiple times this season he has pulled off individual moments of magic that if, coupled with better composure from our other players, would have won us the game. His pass to Zlatan in the Liverpool game being a prime example.
Due to his price tag I understand people expect sudden performances, but how much he cost isn't going to make him mature beyond his years. The talent is there for all to see, he's one of the most talented players of his generation, can do everything. He's also prone to making the wrong decisions and holding onto the balls, showboating at the wrong times etc, but that's all things that hopefully he will iron out of his game in time.
The same people being impatient with him would be the same ones upset we sold him if he was to go on and play somewhere else.
Also, his haircuts and dabs have nothing to do with his mentality.
