Any manager is going to have their own way of doing things and certain areas where they won't compromise. How you judge them is whether they make decisions that impact the squad negatively in the long run. Wenger was ruthless with Wrighty, and it was needed, but he didn't camouflage it as something else; he just relegated him to the bench because he was no longer good enough.
Personally I don't want a manager who would rather work with a talentless but agreeable player than a difficult but brilliant one, and I don't think anyone else really wants that either contrary to any theoretical lines they draw in the sand regarding the misfits. Imagine if Wenger had sold Tony Adams when he showed up drunk, or binned Henry when he told him to fuck off. Or if we had shipped Vieira for his constant episodes; the bloke was a nutter if I've ever seen one, fighting with opponents and teammates alike and accumulating cards at a rate that for years was almost comparable to Xhaka.
Not one of the people here who suddenly think that showing up on time is THE most important thing a player can contribute with would have wanted to rewrite the club history to exclude any of these players. There has to be room for some nuance. Good leaders understand that and pick their fights accordingly; the bad ones don't.
With Arteta I feel like he doesn't want to work with personalitites he doesn't agree with, and the rest is where he is willing to compromise, i.e. in terms of quality. I don't trust the process of anyone who is always taking that stance, especially when that person offers such an extraordinary small amount of good football in return.
