Eriksen's body language is always like that, he never looks bothered but he consistently tops the distance covered stats for Tottenham and is right near the top for the whole league. It's just people seeing what they want to see, he doesn't rant and rave and scream but that's just his way. Doesn't mean his head hasn't gone anyway, but it isn't proof of that at all. I saw someone saying that his missed penalty was proof that he doesn't care as well
