I'm not sure it is irrational. The signs were there last season that the football he prefers will be dire to watch, but he had that unbeaten league run that he's still living of with some fans. I do think if we hadn't won at Tynecastle as well that more fans would be seeing what's actually going on. Signings dreadful, style of play horrible, we won't beat the old firm because he won't try and attack them even at home.I'd sack him now but that's irrational I know. However, him and his players will need to produce quickly.
If we want to get back on track, Heckingbottom needs to go because he's not the man who is capable of making us a top four team IMO.
