Couldn't agree more. Pogba was outstanding in the second half against Newcastle. He absolutely dominated the game, controlled the middle of the pitch offensively and defensively and was far more effective when he broke forward because he could do it in a selective way.
His passing range was superb because by playing a deeper role, he had options ahead of him. Pogba is a multi faceted player but in my opinion he plays his best where there is space. When you play away against top teams, that will be a more advanced position but in games where you will dominate possession forcing the opposition back, that space is in central midfield.
If United want to be a top side, a team that dominates the football in the really big games, then Pogba has to play an orthodox central midfield role.
Why did Pogba play so well in central midfield against Newcastle and so poorly in a similar position in the past? To me it is simply that he decided that he wanted to do it. If he could play with that mentality every game he would be one of the all time great central midfield players.
