Positives: That was an extremely disciplined performance. It's good signs that the players are taking on Mourinho's instructions and the spirit of the players was something we haven't seen for a while. Herrera was an absolute beast, and a special mention to Fellaini as well. He's very good at breaking up play when he's not the deepest player, and has someone to take the responsibility of starting moves off from him. Pogba did a good job off closing passing lanes and pressing their midfielders, but was nonexistent from an attacking perspective.
Negatives: If we set up like that, we have to make sure we aren't as dysfunctional in attack. Rashford was very poor, and made some bad decisions. Ibrahimovic was absolutely appalling. Martial has that left wing spot, but RW is still an issue. I don't know why Lingard didn't play. It's vital Mikhitariyan gets up to speed and integrated into the side because that spot is there for the taking.
