There are also different types of managers, with many different styles.
If we look at football, Ferguson is a gruff, working class Scot who rules to a certain extent by fear. Players would run to the end of the earth for him, because if they dont they will get an ear bending, or maybe get sold.
Wegner at Arsenal is a quiet, educated Frenchman who rarely, if ever, raises his voice. He is totally loyal to his players, never critisizing them in public. But again his players are totally loyal to him.
These two are totally different managers, yet are two of the most successful managers in English football in the last 10 years or so.
Of course many successful football players have gone on to manage in football, but only a few make it to the top. Many try for a few years and then give up.
So there is obviously some "magic" ingredient that each manager needs (in any wak of life) but it can be different piece of "magic" for different people.
