Sunderland have submitted an offer for West Ham's 21-year-old Senegalese defender, El Hadji Malick Diouf. Premier League side Brentford are also pursuing the defender and have made a £40 million bid for the player. According to Senegalese journalist Khadim Diakhate, who writes for DSports, the Championship club rejected Sunderland's offer as it was below their £50 million valuation. The journalist also suggested that a deal might be possible for a fee between £40 million and £45 million. Diouf has 23 caps and one goal for Senegal, joined West Ham in July 2025, and is under contract until 2030. His current Transfermarkt market value is €28.00m.
