Never gonna happen, for that, people need stop picking their guy, move all on the same side and draw a line of expectation/standards and no matter who the fecking manager is, it cant go below that line. No more, they need 3 windows to replace deadwood, they need to bring their players and similar shit, lets see first can you improve those great/very good/good/shit players just a bit, can you improve the team on the pitch, can you implement a vision and idea how to play actual football, before anything. Only in United years are needed to pass for some shit to be judged or improvements to be expected.
Sadly, its time for support to be earned a bit, give him/her time to settle and after certain period ( not 3 years and 600mil. later), lets see if we gonna wonder every game what they doing on a training pitch in a match day threads or not.
Instead, everything will probably be the same, just different manager with different bunch of obnoxious pricks on their high horses backing him up.
