FANCIFUL?
Some of these choices may seem fanciful. But it's clear that the club needs renewal, especially in its top management. My rationale here is to specify people who can unite the club, provide some hope, and gain some direction, which at this point is badly lacking.
Since Sir Alex retired, the club has lacked a major footballing presence at the top of the club. As at when Sir Alex was appointed, managers often directed all footballing aspects, ranging from coaching players, contracts, the media, medical matters, and recruitment.
This model has changed in English football somewhat, with managers now (as Mourinho alluded to) being just head coaches as opposed to managing all footballing operations. Unai Emery at Arsenal has the official title of head coach and not manager like his immediate predecessor Arsene Wenger.
Some United fans have said that merely removing Mourinho is simplistic. I agree with Stephen Howson, in that the issue transcends any tactical/player issues that Mourinho may hold. A successful organisation must have all pieces and structures aligned, but if not, it won't succeed.
The win vs. the Toons was welcome, but more needs to be done for effectual progression. Until then, it may be some time that they win the league again, and City, Liverpool, Chelsea, and even Arsenal or Tottenham, could triumph in this regard before they do.
Identifying a person who can head the football operation holistically, and cover the gaps left after Sir Alex's retirement, would go a long way to restoring United to the top.
