Lyon are in 'advanced talks' to sign striker Bertrand Traore from Premier League champions Chelsea.
The 21-year-old, who made 12 appearances for Chelsea in 2015-16, was loaned to Ajax last season.
He scored 13 goals to help them reach the Europa League final, and finish second in the Dutch Eredivisie league.
The Ligue 1 team's president Jean-Michel Aulas said he was expecting competition from various clubs, but they were keen to do a deal for the Burkina Faso international, who signed a new three-year contract at Chelsea in 2016.
