Due to rules limiting the number of temporary player transfers between clubs, Chelsea cannot send any more players to Strasbourg this season.
The other two players heading to Strasbourg are goalkeeper Mike Penders and centre-back Mamadou Sarr, who joined Chelsea this summer.
Kendry Paez became a Chelsea player in June 2023, after his 18th birthday, when the club signed him from Ecuadorian club Independiente del Valle.
