what do you see on here that suggests he's wrong?
Given all that he has achieved, the results that the club achieves, the points haul ratio he has achieved in his tenure - balanced with the approbation and abuse he gets from a fanbase who have very little experience of recent success - I'd say that HR has every right to say what he does.
In any given conversation that you have personally, if you were getting a constant stream of carping and and abuse from someone in that conversation - what would you do if it was largely unjustified or personal villification you didn't deserve? Would you stand your ground , explain your point of view or fight back by declaring the unreasonable nature of the attack - or would you simply remain quiet out of some misplaced respect for the complainant?
Football fans generally are full of unreasonable expectations and when they are given a sniff of success those expectations go stratospheric - when they are not realised - most fans behave like spoiled brats and want everyone punished, sold or sacked for spoiling their lives. People really do take everything so personally, and I have seen innumerable posts on here with infantile comments about how they are going to suffer at the scorn they will receive from fans of other clubs.
Sacking Harry isn't the answer - look at clubs that have earned long term success, they are virtually all clubs with one thing in common, the same manager over that successful period. Liverpool achieved long term success with different managers, but they were all from the same pool of staff who set them on the road to success, thereby maintaining the continuity factor.
We don't have to be in love with the manager to recognise the success that he brings, to think otherwise is unrealistic and immature.
