According to journalist Ben Jacobs, West Ham expects to receive nearly 100 million euros for the sale of Mateus Fernandes this summer. The club intends to use interest from Manchester United, Paris Saint-Germain, Arsenal, and Real Madrid to increase the price. The club's goal is to double the approximately 49 million euros they invested in Fernandes last year. West Ham expects to find a buyer for the player despite the high price.

According to The Athletic, the Hammers have accepted that Portuguese midfielder Mateus Fernandes is likely to be sold this summer, regardless of what division the club are playing in next season. West Ham’s season has not gone to plan, and there is talk of a major summer rebuild. The Hammers have accepted Fernandes will be sold to help fund changes to the squad. If clubs are seriously interested and the financial offer is significant, West Ham may feel they have no choice.

Paris Saint-Germain has established contact with Mateus Fernandes. The 21-year-old midfielder was trained by Sporting Portugal and played in the Premier League with Southampton in 2024. He was recruited by West Ham for 44 million euros last summer and is under contract with the club until 2030.

Portuguese central midfielder Mateus Fernandes, 21, will seek to leave Nuno Espirito Santo’s team if West Ham United are relegated, as he has no interest in returning to the Championship. Fernandes' contract runs until 2030 and West Ham may want more than their original £42m outlay if they have to sell him at the end of the season. In his first season since joining in August 2025, the Portugal U21 international has scored 3 goals and provided 3 assists in 27 Premier League appearances. Fernandes has admirers in the Premier League and Europe, with Manchester United and Manchester City among the clubs recently linked. In March 2026, West Ham's asking price was reported to be between €65 million and €75 million, while a relegation release clause was widely reported in January 2026 to be set at approximately €32 million.
