I can see both sides on this Dave. One thing I will say though, is I think it's a strength not a weakness for a DOF to be to identify which players are worth supporting the manager with. Like take Richarlinson (who to be fair Brands wanted to sign at PSV) a more inexperienced DOF might have dragged their heels. You see that a lot with DOF, as if to prove a point. I don't think thats sensible.
The broader issue about his role is worthwhile though. I know you've said before you want a quality CEO who can help oversee transfers, working closely with a manager and a competent Head Scout. So it's not that you don't want a structure, but you probably want the roles to just be allocated slightly differently. Theres certainly a case that with a manager like Ancelotti, that would work better.
