United fans: give manager time, we don't know if it's his fault, we have to be patient!
Also United fans: sack the board, the executives, the coaches and sell all players bar Mainoo and Garnacho.
I like this idea of setting up perfect structure with perfect coaches so "any" manager comes in will thrive. Like, let's try everything to make it easy for a manager. That's the top priority.
That's not even the issue, making things easy for a manager is a pretty good idea. The problem is that if you have to change everything then the problem may not be everything, especially when many do more with less.
