If one steps back the hysteria over Allardyce in all threads is really interesting to observe.
Not sure that I've ever been aware of it with a new manager at any club in the past with the exception of Huges going to Stoke when someone parked on a bridge over the M6 with a 'Hughes out' banner the day he signed.
It must be quite baffling to outsiders mixed in with some amusement.
Not hysteria at all. Just a lot of people don't like or rate the manager, based upon decades of available evidence.
