United fans aren't oblivious to the importance of good managers. Most of us spent 30 years watching the greatest manager of all time lead our club.
We also watched 3 different types of managers come in and fail, each leaving the club in a shit state behind them. Two of those were world renowned, successful managers whose resumes piss all over half the flavour of the month options half the people in this thread would have us replace Ole with.
If there was a bona fide Klopp or Pep available to us right now, I doubt there's a United fan alive who would be too upset at us bringing him in. But who is that?
We could hire Conte, have him come in and play 5 at the back playing 2 of Ronaldo, Cavani, Greenwood, Rashford, Sancho, Lingard and Martial every week. We could watch him fall out with everyone at the club over the next 2 seasons, possibly winning a title while doing so, before flouncing and leaving a holy show behind him.
We could hire Zidane, ignoring the fact that many Madrid fans would suggest he has many of the same tactical limitations as Ole, and when he went through a poor patch after a few months, we'd have the same genius Monday morning quarterbacks in here, shitting all over the club and crying about how bad an appointment he was.
Or we could hire Pochettinho, the Emperor without any clothes, who managed to come second with a Billion pound squad in a league full of clubs who would struggle to win League 2.
Find the world class manager who is interested in building something proper at United, and most of us would welcome a move upstairs for Ole and a new technician in the dugout. Until that happens, shut the feck up and support the manager and the club.
