According to ESPN BR, Kevin Castaño was recently a target for Vasco. Vasco, however, prioritized the purchase of the Argentine Santiago Sosa from Racing.

Because the club has not yet finalized a deal for its priority target, Santiago Sosa from Racing, Vasco is exploring other options in the transfer market. Vasco has consequently made an approach for Kevin Castaño, a 26-year-old Colombian midfielder from River Plate. Castaño is considered a secondary option, and the proposed deal is a loan with a purchase option set between 6 and 7 million dollars. Castaño, who joined River Plate in March 2025, has a contract with the club until the end of 2028. The Colombian international has 27 caps for his country and has made 5 appearances in the Torneo Apertura this season. According to Transfermarkt, his market value is €5.00m.
