Galatasaray is one of several clubs monitoring 26-year-old Lazio midfielder Mattéo Guendouzi, whose future is becoming more uncertain. It is reported that Sunderland are also monitoring the player. It is said that Fenerbahce has prepared a proposal of €25 million plus bonuses, although Lazio's sporting director, Fabiani, stated that no official requests have arrived. Atletico Madrid has also shown significant interest, with manager Simeone pushing to sign Guendouzi. Lazio intermediaries were recently in the Spanish capital to discuss a possible sale. Lazio's president, Lotito, values the French player at a minimum of €30 million, and it is reported that he is unwilling to lower his asking price easily. Guendouzi has 14 caps and 2 goals for France. He joined Lazio from Marseille in July 2024 for a fee reported to be €13 million, and his current contract runs until June 2028. In the 2025/2026 Serie A season, he has made 15 appearances, scoring 2 goals and providing 1 assist. Transfermarkt estimates his current market value at €28 million.
