Olympique Marseille president Pablo Longoria won't rule out keeping William Saliba for another season.
The defender is on-loan at OM from Arsenal.
Longoria told La Provence: "It's a three-way question. For the player's owning club, Arsenal, the player and OM.
"We have to see our possibilities. He is very good here, we are very satisfied with his performance.
"William is one of the best young defenders I've seen in my career. After all, everything depends on the three parties. It's a matter of market value. But we have extraordinary relations with Arsenal."
