That has to change. If we're just looking for another Wenger then we're done anyway. It's the philosophy of the club that has to change, just as much as the manager has to be changed. The manager needs to serve the new philosophy, not the other way around as it has been for all these years.
Regardless, the new guy doesn't come in with that "look what he's done for the club" get out of jail free (a thousand times) card. Ridding ourselves of the cult of Wenger will automatically remove many problems.
