It's a clusterfuck of a situation. I think it's fair to say that Amorim deserves more time. I also think it's completely fair to say that they have looked utter shit for the most part under him this far.
Man Utd need a clear out and bring some fresh blood and energy in to the squad and they will be fine next season. Not challenging for CL places maybe but at least having a go at getting into Europe again.
As fun as it is watching one of the traditional "big" clubs failing we all know this feeling as fans, we've been there as well too many times. It's fucking shit tbh.
Add to that the slight problem with totally unlikable owners and an aging, overpaid squad and it's not much fun at all.
As to the debate in regards to Howe vs. Amorim, it's blatantly obvious that Howe had a better first 7 months in the seat than Amorim has had whichever way you look at it.
