Manchester United defender Eric Bailly is struggling on-loan with Marseille.
L'Equipe says the defender is dealing with a "very fragile right thigh" and that injuries are spoiling his time in France.
He has only played 625 minutes this season, with manager Igor Tudor "getting used" to having him at his disposal.
The defender has one year left on his contract, and this spell of injuries could make it harder to shift him on in the summer.
