Board will select a manager and give him resources. Same as Arsene Wenger or SAF or any other top manager. SAF uses those resources to get 200% out of his football team and not worry about player sales profit, pre-tax profits etc.
Most importantly, getting a new manager will answer the biggest question at AFC- is it the board holding resources back or AW choosing to be a butt buddy of the board by maximizing as much profits as possible. I firmly believe its the later..
If they do and we have the same cycle again, we know whose at fault. You peeps in London, get on a strike, make t-shirts () and get those greedy fuckers out! Having said that, if the board are to blame, I do not think the 'middle class- I wont do a thing' mentality of majority of Arsenal fans will do a thing. There will be plenty of 'keyboard warriors' though!
