Valentin Castellanos

In May 2026, Transfermarkt valued the player at €28 million. This followed his completed transfer from Lazio to West Ham in January 2026 for a fee widely reported to be between €29-30 million. Around the same time, a reported €25 million offer from Flamengo was turned down. In late 2025, Lazio's asking price was consistently reported between €30-40 million, with a specific €30 million price for Premier League clubs mentioned in December 2025. In June 2025, Lazio's president claimed an offer of €40 million was made. The player's transfer from New York City to Lazio in July 2023 was for a fee of €15 million.

Our valuation for Valentin Castellanos is anchored by his very recent transfer from Lazio to West Ham in January 2026 for approximately €29-30 million. This fee was consistent with Lazio's reported asking price in the months prior. While he just moved, West Ham's subsequent relegation creates significant pressure to sell, likely preventing them from making a profit. Therefore, we estimate his current value to be slightly below his recent transfer fee, aligning with his latest market valuation.
