Yehvann Diouf, a 25-year-old newly-capped Senegalese international, is a potential goalkeeping option for Chelsea after the club missed out on other young stoppers. Diouf moved from Reims to Nice in the summer and is under contract until 2030, which means any transfer would require a significant fee; his current market value is estimated by Transfermarkt to be €12 million. Last season at Reims, he prevented 14.6 goals, the most in Europe's top five leagues. He has continued his form at Nice, where he has already prevented 1.2 goals, ranking him 20th across the same leagues.
