It wasn't just that he was out of position, it was more the fact that he didn't even sprint back to help the defence out, even N'dombele put in a little spurt when he got close to the penalty area.Sorry but that's not quite right, he absolutely was out of position for the central player of a CM3. He wasn't there to screen the back four on a number of occasions including their first two goals.
My opinion was that he had been told to play higher up, not that it's him being awful. I think he would be a very good CDM if coached appropriately.
