For that particular point Manchester United and SAF are a better example since I suspect that SAF himself is the reason behind that mindset. SAF took over United when they were in a relegation playoff spot(19th out of 22 teams), they finished the season 11th and the following season 2nd. It's the 3rd and 4th seasons that were difficult but SAF had money in the bank due to his previous performances with United but also with Aberdeen.United has one of the most patient fanbases of any supposed “big club”. In fact, I don’t think there’s any other fanbase as committed to “back the manager” as United’s. I have a theory it’s partially because Ferguson was here so long, and partially because many want to hold on to a childish notion that we’re not like other clubs (the “United way” thing is adjacent to this). A manager doesn’t survive a 7-0 mauling by their biggest rivals anywhere else (top clubs). Here, it was largely “shrugged off”and people just moved on.
One could argue that all the bad managerial appointments we made stayed here long after it was clear it wasn’t going to happen, and a factor in that is how reluctant United fans are to put pressure on the club to change direction/cut ties with managers.
For reference (and yes I’ll quote this again):
We’ve been so shite for so long that smash-n-grab wins are reason for people to come to this thread and declare a guy that has us 29 league games in with a goal difference of 0 should be afforded another season - just to see if it “clicks” - now that we have a “structure”. It’s insane.
Most people here would have been happy with evidence of progression in our football. To say this fanbase doesn’t give managers time/is expecting them to compete right away isn’t even being disingenuous - it's an outright lie.
I could be wrong but it sometimes sounds like SAF's story isn't grounded in reality, he did what every other manager in a top club was required to do in order to keep his job which was to hit the ground running and improve the performances of the team drastically. If people really want to use him as an example, the point should be about managers that have performed at a high level for your club, not newly appointed managers that have question marks over their heads.
