Lyon are in advanced talks with Crystal Palace defender Mamadou Sakho.
France Football says OL sports chief Juninho is close to reaching an agreement over personal terms with Sakho's minders.
For their part, Palace are willing to sell and are demanding €5m from OL to settle the move.
It will mean a return to France for Sakho, who left PSG as club captain for Liverpool seven years ago.
Sakho, 30, has been with Palace since 2017.
