The Uruguayan club are based in Gus Poyet's home city of Montevideo, and according to a statement made by River Plate chairman Alvaro Silva, contact has been made between himself and the Sunderland manager regarding a potential deal for the 21-year-old forward;
"Gustavo Poyet called me when he was in Montevideo and asked me about Leandro Rodríguez, he told me 'I need a player of his kind for Sunderland'."
"However, the club's foreign quota does not allow you to take now so surely done in December, although there are other options for the player."
"We believe he will stay with us until December and then go to England"
Little is known about the Sunderland manager's alleged target, other than the fact that the young striker has scored 10 goals in 50 appearances for River Plate and is regarded as the club's finest young talent.
Poyet himself represented River Plate early in his career before moving to Real Zaragoza, and it's the Uruguayan's ties with his former club that may have aided him in reaching the reported formal agreement.
However with any potential deal for the player impossible until at least December, Rodriguez can offer little solution to the current striker crisis at Sunderland and Poyet will need to seek further recruitments elsewhere before The Black Cats are ready for the new season.
Portuguese giants Porto have also been linked with a move for the youngster.
