Yeah, I though the affect of Emery's way was being overstated. Marginalizing a super star is not going to change him at the age of 31. When the team around him isn't functioning, Ozil probably isn't the right player to provide a spark.
The talk of work rate aside, does anyone else think he has lost a bit ability too? He isn't as nimble footed, slightly slower on the turn and inconsistent with his passing even. He still moves off the ball between the lines better than any player we have and provides option and creativity, but obviously a full level lower than how he could.
