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.
The first thing Capello did when he took over from McLaren was teach the England bunch manners - he cut out all the nicknames and made the players address him as Mr Capello. He also made them turn up for dinner on time and stay until everyone was finished. They're tiny things but just show the players who's boss. He also kind of suggested the players basically ran the England show under McLaren's management.
Not best examples really as England in general are still shit under Capello.
Last world cup was laughbly bad.
