Rome wasn’t built in a day, but going for Mourinho after the experience they had with Nero …
I do see do.ob’s arguments about recent coaching experience, big ego experience and likely implementation time.
On the other hand, we know that Team Solskjær made several attempts at making us play a higher line and press earlier, and that this also was his plan for the past season. If the conclusion was that Solskjær had his strengths and the right ideas, but not the acumen to succesfully implement this kind of collective pro- active defence at top level (a reasonable conclusion), then getting Rangnink in to head the same coaching team in the same process would make sense, particularily if there already was an idea that this is the direction of football we would want to continue with under eg Poch or Ten Hag (who both have things in common in this part of the game).
I am not sure wether Murtoughs ideas are theoretically sound, wether he is the right guy in praxis to grind out success, or if the Glazer set up makes it almost impossible, but the decision to appoint Rangnick still seems consistent to me in hindsight, even if it went tits up, and even if there were warning signs.
Cancelling the consultancy project (regardless of whose decision it was first and foremost) also makes sense, looking at how it played out.
