Live updates on transfer rumours.
TransferFeed valuation based on market analysis.
In August 2026, reports state Atlético Mineiro agreed to a loan with an obligation to buy 50% of the player's rights for $5 million (approx. €4.75 million). In July 2026, Vasco da Gama was linked with a loan including a purchase option between $6 million and $7 million (approx. €5.7 million to €6.65 million). His Transfermarkt value was reported as €5 million in August 2026, down from €7 million in February 2026. His most recent completed transfer was from Krasnodar to River Plate in March 2025 for a fee of €12.6 million, following a move from Cruz Azul to Krasnodar in January 2024 for €7.3 million.
Our valuation for Kevin Castaño is anchored by his significant €12.6 million transfer to River Plate in March 2025, but adjusted downwards due to his current status as a sidelined player. The range is primarily shaped by recent transfer negotiations: a reported loan-to-buy obligation from Atlético Mineiro valuing 50% of his rights at approximately €4.75 million (implying a ~€9.5 million total valuation), and earlier interest from Vasco da Gama with a purchase option reportedly between €5.7 million and €6.65 million. The estimate reflects a likely compromise, representing a loss for River Plate but aligning with the concrete figures from advanced talks.
