Premier League leaders Leicester have had an offer accepted for teenage French defender Wesley Fofana, Saint-Etienne have announced.
The deal is reportedly worth up to £30m and is the "largest ever obtained" by the Ligue 1 club.
Fofana, 19, has been described by his club as "one of the greatest French talents of his generation".
He has played 29 times for Saint-Etienne including three games this season.
The French club are managed by former Leicester manager Claude Puel.
Fofana would be the second big-money defender to leave Saint-Etienne for a Premier League side recently after Arsenal signed William Saliba for £27m in July 2019.
