Dear god, he'll definitely learn from it when Martinez and the others discuss it with him. Unlike the Bosnians I think that this should be his learning year: bigger roles in cup games, sub in PL games. Love his play, but he's young and need 1 year to fully adapt. He did this kind of silly moves a few times in the Hungarian league too, at his first match he fall over the ball and his own legs 3 times. Then became player of the year. So it's up to him: a lot of work and submissive behaviour is all he needs.
