I don't think that stacks up TBF.
MON had the overwhelming support of the vast majority of match going Villa fans. Indeed, I'd go as far as to say there have been more successful managers (like BFR, Brian Little) who weren't as popular.
Not that they were unpopular, you understand. More that the support MON enjoyed was closer to hero worship at times.
Fans questioning decisions either in the pub or on internet messageboards is part and parcel of the game. Perhaps his overall appeal was starting to wane. It would have been interesting to see what kind of reaction he would have generated had he overseen a sluggish start to the season or individual results like Newcastle and Rapid Vienna at home. We'll never know - the timing of his departure ensured that if nothing else.
Ultimately he enjoyed more favourable conditions than any Villa manager in living memory, popular extended support from the fans and strong financial backing that outstripped even the likes of Manure, Liverpool and Arsenal in recent seasons.
Even with all that he still decided to bail when he did.
It's history now. GH as an appointment might not have generated the same level of excitement that MON's did back in 2006 - or even DOL's did in 2003. Instead, there might be closer parallels with Fulham's appointment of Woy back in 98. That wasn't an arrival greeted with huge fanfare either. But if -like Woy managed for Fulham- we exceed expectations under GH, I don't think many will ultimately care.
How dare you disagree
Thing is, although you're right about the last manager getting overall support, there were enough against him for him to be booed on occasion.
I'm all for constructive discussion on a manager's decisions, but if it leads to a good manager being abused at VP it's going too far.
