I would encourage all United fans to go back and re-watch the game at West Ham at the end of October. We lost, it was Ten Hag's last match in charge. We weren't great but it was actually a very decent performance and we were unlucky to lose. Our chance creation was really good, our finishing was poor, and we controlled large sections of the game both in and out of possession.
It wasn't good enough and Ten Hag hadn't been getting results for more than a year so he was sacked fair enough. But we weren't "the worst team in the history of Manchester United" when he left. We're there now because of how much worse we've got since then.
There are good arguments for the fact that this is just the pain we have to go through to become an Amorim team and for people who think like that, I think they have a totally reasonable case. I also really hope they're right. But on the basis that all I'm seeing is a team regressing fast (aside from a few decent, but often quite desperate performances against the big boys) I can't really think that's the case.
If Ten Hag had stayed I think his United team finishes 6th-8th and maybe wins the Europa League. Clearly not good enough for where United want to be. But 3 months later his successor has us looking over our shoulder at the relegation spots and using "worst in history" language. Fair enough, but we weren't the worst in history when you arrived, Ruben. You've made us that.
