Many said that about Pogba, it just shows what actual belief and game time can do.
It's not easy coming into a match late, especially when the tempo is usually fast at the end of the game.
He should be given the Mata free role in our team to wonder around and playmake. he is definitely better moving with the ball from a deeper position IMO, but he has wonderful balance and 2 good feet which helps him work his way up the field. I get why Van Gaal has been reluctant recently to play him, but he won't get any better playing at U21 level, he's clearly above that.
