Possibly, although I think there's a lot of mess going on behind the scenes which is why I never felt that replacing Wenger was a silver bullet.
I never thought things could get this bad though.
It had to happen and the best thing about any manager now is they're not Wenger - in the sense that they don't come with his baggage and legacy, they're easier to move on from. But while the mess behind the scenes persists I don't know how effective any new manager can be.
