People here are right, he is gonna make more mistakes at some point. But I guess look at it from Arteta's point of view: he's starting a daunting new project and he needs help with that, he needs voices in the dressing room he can trust to manage the other players a bit. It's probably why he likes Xhaka so much too.
If he had decided to let David Luiz go then maybe he'd be thinking we're not experienced enough in the dressing room, we're lacking leadership.
