I used to feel the same about Man U but its a sign of how bad they are that I barely notice them now, only this sacking bought them to my attention as they have been also rans in the league for so long now.
They were essentially Ferguson United when he was there, an all time great manager who was everything at the club and it has crumbled since he has left, not certain the weird INEOS football but not club owners is going to help them much at all and I don't think a Ferguson is out there to save them (the closest thing is very near by but he wouldn't touch them with a bargepole) so the future looks bleak until someone can properly save them from the Glazers and find and give a good manager a fair chance.
I actually feel a tinge of sympathy for the proper Man U fans and the institution itself, they probably deserve a bit better than the current shitshow, not like you can even gloat much at the glory fans as those lot have gone to ground, never even see them in the Surrey heartlands anymore.
