There was friction - allegedly. Bet he wishes he'd agreed to work with a DoF now. Given the choice of DoF or committee, who would choose to work with a committee where there has to be a consensus on every decision? Anyway it's old news now, onwards and upwards.
If we had got a DOF, it is rumoured LVG was the main candidate for the job. If LVG were our DOF then MU might have a competent manager now. With their resources they would quickly become very dangerous again with a competent manager.
