I think if you take in the full range of opinions I've expressed about Pep over the last 6-12 months, you'll get a clearer picture. I'm not fully #PepOut, but I have questioned - after some bad results this season which have reflected a lot of problems from last season - whether he's the man to get us back to the top. But I've also said, on many occasions, that I'm happy for Pep to continue as our manager because he's earned that right. I've also said numerous times that I think he'll win us the league again at the end of the 26/27 season before bowing out and that I'd be gutted if he left now or at the end of the 25/26 season. I'm doubtful over whether keeping him beyond his current contract would be the best thing for City long-term, but I wouldn't say I'm 100% of the opinion that "Pep needs to go". In a weak moment after the Leverkusen game, or after the Brighton and Spurs games this season, I might have made some off-hand comment wondering whether Pep is currently in his late 2000s Wenger phase, but I'm still broadly on board with him staying and would be sad if this season did end up being his last.
At the same time, Amorim has been at United for about 12 months now and I think it's fair enough to point out that they are currently in a better position than they were when Ten Hag left. They were 14th in the league when Amorim was appointed and they're currently 7th. I don't know if Amorim is "good". I've said in the post you've quoted that I don't think he'll be the man to win them a Premier League title because they're currently too far behind City, Arsenal, Liverpool, and Chelsea (and arguably Villa). But I think it's beginning to show that the more influence Amorim has on the squad, the better football they seem to be playing. They're currently 3rd in the xG table, which tends to show itself in the real table as the season carries on, and I wouldn't be surprised if they finished between 4th-6th with the way this season is shaping up. That's not to say they're "back" or that they've "turned a corner", they're simply showing improvement on the last days of Ten Hag and the early days of Amorim. That doesn't mean I think he's a better manager than Pep - I'm just wondering if United are at the beginning of a good cycle with a new manager while City might (might!) be reaching the end of a good cycle with the guy who's been in charge for 9-10 years.
