There is a sizeable Arsenal supporter contingent that wants Arteta out. I personally don't get it, but I know football fans are a fickle lot. He is not at the Klopp or Pep level yet but I think he can legitimately get there one day. He is growing tactically. There are very few games we are getting outplayed and as good as Wenger was, we were looking pretty bad versus the top teams in much of the last decade of his time.
I feel he second guesses himself a fair bit still, but there is no other manager out there other than those two I would trade him with. Along with the squad, there is room to grow and I am hopeful we will under him. I am not so sure he is staying all that long for some reason though.
