The Colombian is seemingly wanted back in South America.
Aston Villa certainly strengthened in the central midfield area this summer. The arrivals of Idrissa Gana Gueye and Jordan Veretout mean that the club's central midfield position looks to be one of their strongest.
Ashley Westwood and Carlos Sanchez are already with the club, although one of them is catching the eye of a fairly ambitious South American side.
River are fearful of losing Matias Kraneviter in the winter, along with Uruguayan namesake of the Villa star Carlos Andres Sanchez, meaning the Villa Sanchez is high on their list of priorities.
River Plate have been in great form recently. They won the Copa Libertadores in August and are establishing themselves in the Argentine Primera Division once again after a shock relegation to the Argentine second tier in 2011.
However they have seen their bitter rivals Boca Juniors continue to conquer the transfer market - with the likes of Carlos Tevez, Nicolas Lodeiro and Dani Osvaldo all joining the club in recent times.
River are therefore hoping to pull off a coup of their own with Aston Villa's dynamic midfielder seemingly on their list of targets.
