To be fair the mindset of Arsenal being a business will stay with or without Wenger, there are no football people on the board apart from Gazidis and he is essentially shackled as to what he can and cannot do. He brought in Wim Jonker and Shad Forsythe behind Wengers back.
I think unfortunately things may improve with a new manager, but with a new manager the bottom line is that the most important thing for the club is the bottom line.
