@CO88LER5 Athletes and professional sports people have huge egos: each time there'll be a handful that think: "I am going to be the one who turns it around at Man Utd..." - really, a lot think that way, also because the one that sooner or later will bring back glory is going to be considered a club legend: the one that ended the drought.
And they tried it with the biggest managers (Van Gaal, Mourinho) and with a proper club person (Solskjaer), they tried it with esteemed veterans (Ronaldo, Eriksen), with half of the 2019 successful Ajax-team (and staff), I mean: they literally tried everything in every way for the last decade.
It's a little too late for it now, but in my view they actually ought to talk down expectations (get the pressure off), reset and reboot and aim for success in -say- 2028, according to a three-year plan. Buy yourself time and space to implement a structure, an organization, a vision, an image, etc etc. similar to what happened at Liverpool when Klopp joined, or Arteta at Arsenal - they also made it very clear that they do expect a high level instantly, but trophies and silverware a little later. Man U need to apply the same strategy, which comes down to clear communication to the fans and clever marketing to the outside world: they are a big brand after all.
