Eh. You saw the exact same thing on United forums when he had that good run with us at the start of 20/21 - oh, we should have given him more time, backed him, etc.
In both cases, I don't think people are accurately remembering just how utterly toxic his final days were. Every match was a pain to watch, and his tenure was the first time I skipped out on some games entirely because I had better things to do than watch us sit in our own box, get battered for 90m by everyone from City to f*cking Dinamo Zagreb, and either win through sheer luck or draw/lose because someone conceded a stupid goal after 90m of relentless, entirely avoidable pressure.
He made watching Spurs miserable, and at the end of it, I was relieved when he was gone - of all the sh*t I have ever given Levy, sacking him ranked amongst one of the best decisions he ever made, and I'm just sorry he didn't make it sooner. like after the infamous Zagreb collapse.
After the year we've just had, with Antonio Conte proving to the entire world that a bit of fitness, a bit of belief, a bit of tactical acumen, can transform crap players like Dier, Sanchez, Doherty and Davies into one of the meanest sides in the league, Mourinho has no excuses left.
What did Mourinho ever do to improve *anyone*? He left behind a disaster area - the most unfit, demotivated, broken squad in the league, set for the 2022 equivalent of the Intertoto Cup. Hooray.
