That was a good performance and surely something he can build on. He kept it simple and let his teammates, mostly, Herrera and Fellaini, dictate the play while providing his excellence whenever needed.
He did not try to force things and be the best player. This is what I like a lot. I was very happy to see that Mourinho and the management have identified this issue where he tries to be too involved and tries to force things and ends up making mistakes. Today he patiently allowed the play to come to him. I liked this version of him very much.
He will get his chance to be the best midfielder in a match, but it can't be every match. There are so many factors that govern that, like the type of opposition, how the opposition sets up, our tactics and his own energy levels. Yesterday was Herrera's day. Herrera was completely in his zone, closing down players, providing assists, breaking down play. Fellaini too, who loves this hard shove and battle type of matches. In such situation, it is best to just let your teammates do their work and assist them whenever necessary and he did that to perfection.
If we continue playing the way we did yesterday, I think the Herrera - Fellaini - Pogba midfield is not too bad.
