Managers?

[Faz!]

I'm basically looking for information about the Agents that manage players, so for example, looking at Kaka's manager, His Name, and his role that he plays for Kaka, the actions he takes on behalf of kaka, e.g. Press Conference, Public Relations, Financial Dealings, Player market Evaluations( How Much he's worth), his Psychological help, his Physic Ability and his contracts signings and basically everything the Player manager does when he manages a player. Please do this for C. Ronaldo aswell cus i need info on more than one player to compare and contrast both the roles of both managers for those two players, and then compare them with the other career that i have chosen, that is, "Sports Business Manager i.e. The CEO/manager of a sports organization". Basically for that im picking random organisations like fifa, nrl, ICC, or just clubs like the bulldogs and swans and just checking out what the role of the CEO and Manager is. and then comparing it with the role of player managers.

This is for my assignment...so I just need info on Kaka and C.Ronaldo's managers as stated above....please help me guys.
