Wenger as general manager with somebody like Arteta as first team coach until he is ready, if ever, to become manager.I'd take him in a heartbeat either as manager or director of football, hell even as CEO.
As a manager he'd have a point to prove, wouldn't work with some joke dof so we'd have to restructure meaning bye bye Walsh get him with a young assistant like arteta and I'd be happy.
As a dof, he'd set the clubs style up with no room for arguments for a decade and managerial appointments would be chosen that suits player recruitment.
