And Sir Alex himself has in both of his books, one on leadership, advocated the complete opposite: that the manager of a football club should be the one in charge completely of everything football related.
We have a tradition at this type of governance at this club and it is not so easy you just throw it out. Especially when you have employed a manager in Mourinho who saw this as the main reason to come to United. IMO that was the case at least.
We have an advisory Board of Directors at United, where the great man himself is a Director. Full of "football people" that fans are crying about to have more impact on the club. I would argue that these "football people" are the ones that opposes a DoF-role at United.
Objectively Woodward himself distanced himself from the football side of things more or less completely when he surrendered the negotiation of contracts, etc to Matthew Judge in 2016. Since then we have been moving toward an organization that would be able to implement a DoF.
When (not if) that will happen it will not mean that Woodwards responsibilities will change. It will move power and responsibilities from the manager and Matt Judge and probably a bit from Lawlor; the head of scouting as well: to the DoF. It will not do one iota about Woodwards role.
There will be and is people at the club opposing such a transition though, not at least the great man himself.
I wish that people at least would read up on what our current organization really is like. I dont adore Woodward, but he gets far too much shit for stuff that he is not responsible for.
