PSG coach Laurent Blanc admits Mamadou Sakho could be sold.
Blanc would rather not part with a player of such promise, but appreciates that Sakho may decide to take on a new challenge.
He told L'Equipe: "When a player wants to change his club you have to offer an argument that makes him want to stay.
"You also have to look at his status is in the team. If that status won't change, what can you say?"
