Valentin Castellanos

In January 2026, reports converged on an imminent, agreed transfer to West Ham for a fee of approximately €29-30 million. Throughout late 2025, Lazio's asking price was consistently reported between €30 million and €40 million. During this period, a reported offer of €22.5 million from Flamengo was deemed insufficient. In July 2025, Flamengo was reportedly prepared to offer over €25 million. An earlier offer from the City Group in July 2024 was reported at €15 million plus bonuses. The player's transfer from New York City to Lazio in July 2023 was completed for a reported €15 million.

Our valuation is driven by multiple, consistent reports from January 2026 indicating that a transfer for Valentín Castellanos from Lazio to West Ham has been agreed upon for a fee of approximately €30 million. This figure aligns perfectly with Lazio's frequently reported asking price of €30-40 million throughout the second half of 2025. The agreed fee represents a significant increase from his €15 million transfer in July 2023, reflecting his performance in Serie A.
