Crystal Palace are leading the race for Lyon defender Joachim Andersen.
The Dane is up for sale at OL after a successful season-long loan with Fulham.
Le 10 Sport says Palace are now in talks with OL over a deal for Andersen, who is eager to return to London for the new season.
New Palace manager Patrick Vieira is a fan of the defender, though the deal was being pursued before his appointment.
OL would prefer an immediate outright sale for Andersen.
