Whole saga shows how idiotic getting rid of Koeman was.
I never thought he was the right man for the job, but you only get rid of someone if you have a plan in place to bring in someone you think will perform better.
What has followed after his sacking shows that the problems run deeper than the manager. It's lazy and too easy to say "oh Koeman was shit" or now "oh Unsworth is sit".
Whilst in my opinion Koeman wasn't the long term solution, in the absence of a good replacement we'd have done better to keep him for now, trust that he almost certainly would've over time brought some degree of stability in this season, before then reevaluating and maybe recruiting a new manager from a position of greater strength, rather than the freefall shitshow we are now.
