Why leave the owners and board out of the firing line? They should be getting just as much shit for all of this.
I agree they won't just up and leave if 500 fans shout ill-thought chants at them. But they should get some of the heat.
Wenger has made a rod for his own back, and is 100% culpable for the failure on a footballing level. But Arsenal has lost more than just games of football. It's lost its soul (although Wenger is responsible for some of that too).
