It wasn't a particularly good game. They tried to talk it up as a clash of the coaches and carried it on from there, but really it was nicking a couple of goals and then playing counter attack. Even this version of Mourinho can still do that, it's not brilliant but works.
Rashford had a good game because he was direct and worked hard. I still think he's just another Walcott; fast and good dribbling, maybe even has inferior technique than Walcott, some of his passes are crap.
I don't know what Pogba even does in half of the games. He plays some nice diagonal passes and little dribbles here and there, he's a passenger too much. Shame, he would have been good in this Allegri team....
