"Paolo Rodriguez, agent of Sporting DM Agostinho Ca, who is to sign for Barca B shortly, has threatened to sue the player if he joins FCB."
"Paolo Rodriguez claims he had an agreement with Inter for Agostinho, but the player rejected it, and had a deal with Barca via other agents."
"Thus, Paolo Rodriguez who claims to be the sole agent of Agostinho Ca, says he will sue the player for 1M, if he joins Barca B. [via sport]"
What I don't understand is why the agent would sue if Sporting and the player didn't want to make a deal with Inter.
