Definitely and we shouldn't have knee jerked into appointing Allardyce . You could name 10 Managers who wouldn't be good enough and they would all be better than Allardyce . That for me would include Hughes , Silva , McClaren , Hodgson , Puel , Van Gaal , Dyche , Rodgers without even trying too hard . Shambolic .
I agree with the @Shogun
's premise that Koeman is a better manager than most those managers or many of the options we have. His problem was that he wanted to build play, have some possession and we had no experienced players who could do that in the setup that Koeman has always played. Even though they might seem a good fit, it's been tried and it failed in current circumstances, he might be a better manager than others, but we know it doesn't work and nothing has changed since.
Would have taken LVG, he's always tended to blood younger players and has often left a very good base for the next manager to inherit. He has a better range of systems and styles than most of them, so think he could have found a way to make something work. Plus he would potentially enable a better quality of signing than Koeman, Allardyce could attract, and has unfinished business from United spell.
I think the way out of the circumstances was to improve recruitment, which we couldn't do in September/October, and or find a manager who could utilise the squad in a different way, different formation, play more younger players etc. What we've gone for is a poor copy of Koeman, who is more agricultural and even more hard arsed.
