It has yes, look at managers like Pullis at Boro struggling to make playoffs, managers like allardyce and moyes don't even get considered for jobs anymore, Mark Hughes is another. The premier league has changed as well the big teams rarely lose to the lesser teams now. Warnock performed wonders to get us up but is totally out of his depth in this league. As a club, I think it is pointless to have another Warnock season and then he retires, time for a change now so we can rebuild now.
