He's a very individualistic player, not that all of us don't already know that.
Not the type of guy you want in a struggling game, he'll just stand there and wait for his chance to #YOLODAB his way past an opponent or two before refusing to pass.
Having said that he'd look a lot more comfortable in big games if he wasn't playing with fucking Fellaini in a midfield 2 where the opposition can basically ignore the donkey beside him and focus on Pogba.
