Why do people insist on writing this stuff.... "when Sir Alex left." He hasn't left, that is part of the problem, he is part of the problem.
Furthermore, when he was the manager of the club, not an associate director/consultant/ambassador or whatever he is now, did he ever have to face 9 or 10 well funded and well organised rival teams? No he did not. Did he ever have to go up against teams that get 95-100 points like City and Liverpool do, who play a modern type of football with sweeper keepers and press resistant skillful players? Again, he did not. So why does the club, two weeks ago, enhance Alex Ferguson's role in the organisation and expect it to help? It is time for a reset*, people need to stop eulogising about the past and we most certainly need a break from it now, because what worked then is not going to work now, be it dominating in the transfer market or dominating on the pitch because everything has changed.
*Sadly a reset could have happened if Ralf Rangnicks advice had been acted upon, but no, he was fired because the dinosaurs and the money men, didn't fancy it.
