It's occurred to me that many people believe that should Mourinho return to Chelsea, Emenalo will be forced to leave. The assumption being that Mourinho left the first time round because he didn't have total control over transfers and the general direction of the club, clashing with the board and then-director Avram Grant. This leads many people to believe if he were to return he would want absolute control meaning no more director(s) of football.
I'd like to draw some attention to this discussion between Pat Nevin, Gianfranco Zola and Frank Lampard starting at the 5:55 mark where they discuss the role of the director of football. (Even if you're not interested in this topic it's still pretty dam cool to see club legends chatting on the same table) CLICKABLE LINK JUST IN CASE
Essentially, Zola says that although the position of DOF is above that of the manager (as the person who reports directly to the board/chairman), the DOF is supposed to do what manager ‘tells’ him to do (ie sign this player or this type of player, extend this contract, sell this player, scout him, sack him etc). If there is a good working relationship between the two, a DOF effectively saves the manager’s time and energy so that he can focus on the footballing side of things. Now I don't know what Emenalo's exact role is and if he has any political agendas within the club, but if something like that can be worked out between Mourinho and Emenalo I think it would be great for CFC.
