I've always been mystified as to why a Chief Scout shouldn't be a club appointment rather than that of the manager. That way if he leaves all his dossiers and knowledge of certain players remain with the clun and not just him/the manager.
I can understand that certain manager's want to retain certain scouts as they will either know what type of players the manager likes, or has a great track record of finding the desired player. But for the club to allow the stability, and knowledge, to simply walk away has always bewildered me.
