Olympique Marseille is interested in Karim Coulibaly, an 18-year-old Werder Bremen defender and German U-21 international. The Ligue 1 club faces competition from other teams such as Paris St. Germain, SSC Napoli, and two Premier League clubs, Newcastle United and Chelsea. These latter two English clubs have already held serious talks with the player. Werder Bremen is asking for €45 million for Coulibaly, but a concrete offer has not yet been submitted. The player, who also holds Ivorian nationality, has a contract until June 30, 2029, and a market valuation of €22 million, according to Transfermarkt. In the current 2025/2026 Bundesliga season, he has played in 22 matches and scored 1 goal. During the 2026 winter transfer window, the club reportedly rejected multiple offers, including one for €20 million and another described as 'significantly higher' than €20 million.
