Valentin Castellanos

In September 2026, Everton reportedly prepared a deadline-day package valued at £45 million (~€53 million), with a base fee of £40 million (~€47 million). His market value was listed by Transfermarkt at €28 million in July 2026. This followed his completed transfer from Lazio to West Ham in January 2026 for a fee of €29 million. In late 2025, while at Lazio, his asking price was reportedly between €30-40 million, with the club president mentioning a €40 million offer in June 2025. His prior completed transfer was from New York City FC to Lazio in July 2023 for €15 million.

Our valuation is driven by the very recent and substantial deadline-day bid from Everton in September 2026, reportedly a package worth up to £45 million (~€53 million). This indicates a significant increase in Valentin Castellanos's market value since his €29 million transfer to West Ham in January 2026. His solid goal-scoring record and continued interest from multiple Premier League clubs, despite his team's relegation, support this higher valuation.
