The sulking and mirthlessness would much easier to overlook if he was playing well, which he isn't. Today he walked straight to the locker room after the match without acknowledging the traveling fans... it's the least the players could do after fans travel quite to Swizerland to watch them put down that pile. He also got himself a silly yellow for putting his hands on a player's face. That and he's clearly not in sync with the rest of the team in attack, clogging channels, not making runs, or making the wrong ones. All of that could be resolved with time, but the attitude thing is a trademark, and one he needs to lose.
