Arteta will never change that drastically against Pep as the "Daddy syndrome" runs deep. In fact I am starting to believe that Arteta manages the Arsenal with a lot of WWPD (What Would Pep Do) coursing through his mind. I also suspect Jesus and Oli Z were willing to move to The Arsenal because it had all been worked out what their roles were going to be, which is just like at ManCity but with more playing time.
This is not a 100% bad thing, but it will always come back to bite us when we play Pep's mercenaries.
