But that's exactly the case. He is shockingly unversatile.
He has all the freedom to go forward that he had with us, as every time I watch them play he spends the majority of the match joining the attack... but the difference is that he is expected to return deeper, and to start out play from ManU box and defend back to the goal-line as well.
People saw him as a box-to-box CM here but he really wasn't and spent very little time back around our box. He isn't hard-working or tenacious enough to play that sort of game, to be effective over that bug an area of the field and it's showing. But he's also not quick enough, too poor in the penalty box, and slows down play too much to be a good CAM... so he's really only effective playing from just inside his own half to the edge of the opponents box, creating chances and helping build attacking plays. And he's clearly world class at that, one of the best in the world in that specific role, but without becoming better at finishing/final ball assists, or adding a much better defensive element to his game, there's no way he ever even sniffs the ballon d'or top 3.
