I'd try to explain the agents details:
Krasic's only agent is Dejan Joksimovic.
Naletilic, who is also an agent, is the mediator between CSKA and Juve, he is not representing Krasic, rather the Old Lady. And Borozan is the dump tank to the media used by someone involved, it explains why it is so much of him and his interviews everywhere. But he is not Krasic's agent.
