I honestly think finishing 4th would only serve to perpetuate the status quo, i think finishing outside the top four is the shock disappointment the club needs to stir itself out of it's comatose state, the very idea that we would spend lots of money on players in the summer is a pipe dream. But i think a complete collapse would cause Wenger enough disappointment that he would leave and the long term repair could begin, hopefully starting with Kroenke bringing in his own people.
