I loved Horton. Felt sorry for Royle, Keegan and Pearce. Felt a bit for Hughes too but a lot less so (given that I wanted him gone after Spurs - as the owners said there was just no sign that things would improve) and that evaporated once the media went all over the top.
I wanted Sven out big time. Nice man but a very average manager IMO. No pity there. Or for Reid, Ball, clark, etc, etc.
Ferguson outlasted 18 managers and they had success but IMO not one of our lot would have had half as much success had we stuck with them. even my favourite ones. We simply weren't as blessed as united with players, marketeers or financial riches. We are getting there now and for that very reason I don't mind shopping around to get the right long term manager, i.e. more may have to come and go until we find the right one. Once the owners stay and continue to bring in great talent then I'm not bothered with a few more changes.
