Flamengo's move is a response to the selection of Marcos Rojo, who played for Estudiantes in the semifinal against Flamengo. Rojo was previously with Racing, where he had a transfer marked by controversy. His contract with Racing was due to expire in December, but the club refused to release him to a rival. Estudiantes paid a reported US$ 500,000 to complete the transfer and secure Rojo's services. The transfer was authorised by the Court of Arbitration for Sport (CAS), which is the tribunal of the FIFA, after Conmebol had rejected Rojo's registration.
