No, l cant agree with that. Sure, Wenger has to take some of the blame, but the Arsenal hierarchy are just as guilty. Some examples:You reckon? Arsenal is a fantastic job for any manager. They had become a laughing stock for one reason only: Wenger
Forcing out Dein, who was effectively their director of football.
Adopting a business model which put match day takings above sponsorship in financial importance, hence all the money spent on the stadium. They forecast that , outside the main sponsor, there was no real money. Thay didnt see the pre-eminence of the prem on world wide tv. (They have changed their tune now.)
Large divis going to the owners ahead of the team.
A bonkers transfer policy, viz buy a lot of players who are just below top standard, rather than fewer top top guys.
Wage policy that paid players too much and miscalculation of Prem's own FFP rules.They have sold several to avoid sanctions. Arsene said " if i had known ffp would have this effect, i would have voted against it" (simple maths would have helped him forecast).
Failure to plan for contract renewal, with several running out at once.
Etc etc
So not all Wengers fault.
