He should probably stop turning his head randomly in different direction like he has some problem with his neck whenever camera is showing him without the ball and fixing his hair, and instead probably comunicate more with his teammates, follow the game, etc. He doesn't look like a bad bloke, actually I am sure he is decent guy, but he looks exactly like 13 year old boy who have his crush watching him from the stands for the first time and you know he wants to impress them by his behaviour.
I think the stage is still too big for him, unfortunately, I don't think he ever looks relaxed and composed, even if we ignore that he isn't the most talented player in our squad.
