Controversial football agent who's worked with star athletes, but has a reputation for his outspoken remarks about teams, players and coaches as well as his questionable business practices. He's referred to himself as the "most hated businessman in Brazil."
He's lived in Brazil.
In 2017 he was convicted of tax evasion for having claimed far less income than he actually earned over the course of several years. He was sentenced to five years, but was able to serve it in a semi-open halfway house as well as being able to travel abroad if he chose to do so.
His daughter received physical threats during a particularly nasty and public negotiation for one of Ribeiro's players to move to Real Madrid.
