Everton are interested in signing West Ham United striker Valentin 'Taty' Castellanos and are reportedly seeking to benefit from West Ham United's relegation to the Championship. The 27-year-old Argentina international, who has two caps for his country, joined West Ham during the winter transfer window and scored six goals in 18 league appearances, but was unable to prevent the club's relegation. According to Matteo Moretto on 2 July, Everton are one of the teams interested in the player. Fulham are also said to be interested in signing him. Castellanos' contract with West Ham runs until 2030, and his market value is €28 million, according to Transfermarkt. His transfer from Lazio to West Ham in January 2026 was for a fee widely reported to be between €29-30 million.
