The business side of the game is so different to the footballing side, most managers are ex players and so have a very good knowledge of the game but chairmen who understand the footballing side are much much rarer. Cortese has taken to football like a duck to water for the most part, finding a good CEO to head up the business side would not be hard, but one who can balance footballing and business concerns like Cortese I'm much more doubtful.
