re: So Marcos Rojo's rights are owned by sports agents

Yeah, Porto wrote the book on how to profit from buying and selling South American players under third-party ownership.

Third party ownership is banned in England after the Tevez and Mascherano to West Ham saga, but is still highly employed in many second-tier leagues.

The problem is that many emerging South American talents are lured into signing these shady deals, because they don't have the means of marketing themselves to big foreign clubs.

It's a huge detriment to Brazilian football especially, because these investment groups like Traffic Sports, have no interest in the actual development of promising player. Their inherent purpose is to profit from transfers.
