Napoli are monitoring West Ham United's 21-year-old Portuguese midfielder Mateus Fernandes, whose potential departure has become more likely following his club's disappointing season and the prospect of a major rebuild. West Ham have placed a valuation of €50–60 million on the player, a figure that is expected to decrease if the team is relegated. Inter and Juventus are also monitoring the situation, while Manchester United, Arsenal, Paris Saint-Germain, Atletico Madrid, Chelsea, and Aston Villa have also shown interest. Fernandes, who joined West Ham in August 2025 for a reported €44 million, has one cap for Portugal and a contract that runs until 2030. His current market value is listed by Transfermarkt as €35.00m.
