Mahdi Nicoll-Jazuli is a 16-year-old midfielder who holds a French passport, as well as English and Australian citizenship. He has been capped by England at the U17 level. Paris St-Germain and Bayern Munich have shown interest in the player, who has had options to move to other clubs. Despite this, Nicoll-Jazuli is expected to stay at Chelsea, partly due to the relationships he and his family have established with senior figures at the club. It is anticipated that he will sign a professional contract when he turns 17 in January, and he is likely to make his competitive debut for the team sometime this season. In the 2025/2026 U18 Premier League season, he made 25 appearances, scoring 2 goals and providing 3 assists.
