St Etienne defender William Saliba has suffered a fresh injury blow while on-loan from Arsenal.
ASSE coach Claude Puel has confirmed to the club's official website that the 18-year-old broke his fifth metatarsal against Monaco at the weekend.
Saliba had only been back to full fitness for five weeks, having had to undergo an operation on an abductor muscle injury.
After securing his signature in July, the Gunners allowed Saliba to return to his parent club in order to continue his development before arriving at the Emirates.
But this latest injury will be another blow for the young centre-back's progression.
