I think top managers have something coaches do not. An allureness about them. I've a book on how business can learn from football and top sports when dealing with management and they talk of Fergie quite alot and say that he never gets too close to the players, and has the aura of a father figure that they love but fear at the same time.
McClown's problem is he has always been far too matey with players, so they automatically see him as no threat, that they can do what they want without fear of his wrath so to speak. Top managers have a stern coldness underneath their exterior. Fergie, Clough, Mourinho, Hiddink, even Dither. You just wouldn't **** them about really.
