Emery lost the job by re-instating Özil. Arteta always knew it was a sensitive situation when he came in, he can't drop Özil instantly and turn against a significant section of the fan-base before winning over them, of course he was going to say nice things about him to media. He first gave him some good run of games in which Özil didn't have much impact, after lock-down the fitness of other squad players may have drastically improved which meant it was right time to push him out. I saw the initial run of games under Arteta, Özil was doing the bare minimum and Arsenal fans were raving about him like he had put KDBesque performances. There were at least 5 players in each of those games who had a better game than him. Literally everyone except his fanboys knew he would struggle under Arteta too, the game has moved beyond him and he won't start for any team in the PL. He plays in a dead role, one dimensional, one footed, passive for large periods of the game, no weaker foot, can't press, shoot, dribble, hold the ball, draw fouls or even win headers. Özil's brainwashing is on another level, his fanboys will defend him if he burns their house down. Why would Arteta not play him if Özil makes the team better and can finish higher up the table, he cares more about his career than having some personal grudge on Özil. His fanboys will ignore 1000 proofs that he is finished, but they will cling on to some random quote Arteta made when journalists asked about Özil. Did you really expect him to come and say 'He's sh*t and a social media fraud' ? Truth will come out once he leaves, if they tell it now not even one buyer will come for him.
