Even SAF, by the time he retired, was a little behind in terms of the way football was evolving. Things likes pressing, retaining the ball more strategically, playing extremely fluid football, were not how United played (for the most part) after Ronaldo left. However, the massive caveat here is that Sir Alex Ferguson, when he retired, was more or less ready for retirement. The man is a legend, leader, and an archetypal father to us all. But he is not immortal and no one can stay at the top forever.
A younger SAF, however, would have 100,000% adapted to the way football is currently being played, and would definitely be up there with Pep at the moment. I'm more than sure of that. Even with the current players, heck, we might not be top of the league, but we would be playing better, we would be more inspired as a football club, we would have a clearer set-up, the mood of the fans would be better, and most importantly - even if none of that was the case for a while and we were in transition - the club would still have a clear vision forward. In terms of the football. In terms of the goals. In terms of recruitment. Even in terms of the atmosphere around the club as a whole.
Unfortunately Sir Alex is basically just a fan now, just like the rest of us. Although he may have some remaining power in the board, he probably enjoys spending his time with family and/or doing other things. And so he should. The more time that goes on, the more the man will become a myth more than anything else. And so he should. He will become that for a reason. Think of it like Batman - after his death he is more like a symbol to the people of Gotham than anything else. If after Batman is gone there is a tragedy in Gotham, it doesn't help to say "Even Batman wouldn't be able to sort out this tragedy". First of all, you don't know that. Second of all, the best thing that Batman did for the city is not to get rid of the tragedies of the time, like crime, or the Joker, or whatever. It was to give them a symbol and a vision to strive towards. It's the same with figures like Sir Alex. He has given us a vision to strive towards, as a club. The way Cruyff did for Ajax and Barca. And that's what we should be following - that vision.
This doesn't mean we need to be looking for any young Scottish manager called Alex. It doesn't mean that at all. It just means that EVERY SINGLE DECISION that the club makes from now on should be with that very vision in mind. Every decision, be it managerial, DOF-related, hiring the tea lady, whatever, should be made with the question 'Is this course of action in line with the fundamentals of this football club?', 'Is there a congruence between this decision and the "blood" of our football club?'.
Mourinho has to go. And so does Woodward. They probably won't go soon, I don't mind. I'll wait and I'll still watch the games and read the caf. But I hope that one day soon we begin moving in that direction. I'm an optimist so I think we will.
To conclude:
SAF = Batman.
