TCIB has it right. Pogba would have made absolutely no difference yesterday. The fact he seems to have no defensive or positional discipline would have made it easier for us.
Rags seem to think they would have won with him, yet when you ask them to explain why, they have no answer. Would he have made any difference to their 35% possession and 60 odd % pass completion? Absolutely not. If you can't get the ball or keep the ball then you do not win football matches against better teams.
Pogba is a good player but he's a bit of a show pony. He is an icing on top of the cake type player. The problem for United was that they did not need icing yesterday, they needed a cake.
