River is in advanced negotiations with Atlético Mineiro regarding the departure of Kevin Castaño, a 25-year-old Colombian defensive midfielder. The discussions concern a one-year loan. The main point of disagreement is whether the deal will include a purchase obligation, which the Argentine club desires, or a purchase option, which the Brazilian club prefers. Castaño, who joined River Plate in March 2025, has a contract until the end of 2028. His current market value is €5.00m, according to Transfermarkt. The midfielder has 27 caps for Colombia and has made 5 appearances in the domestic league this season. Vasco da Gama has also been recently mentioned in connection with the player.
