The 19-year-old defender will become the most expensive outgoing player in the French side’s history with his move to the Premier League
Fofana, 19, has attracted strong attention from the Premier League this season thanks to his performances for the French club.
The youngster made 24 appearances in all competitions in 2019-20 prior to the season’s cancellation in March, scoring twice.
West Ham had also moved for Fofana, while Leicester saw several bids turned down.
But Saint-Etienne have now confirmed they have agreed to a record approach estimated at £30 million ($38.5m).
“AS Saint-Etienne reached an agreement on Tuesday evening with Leicester, the current leader of the English Premier League, for the transfer of their defender Wesley Fofana,” the club revealed in a statement published on their official website.
“The amount of this transfer is the largest ever obtained by the club.
“The decision to sell the player was taken collectively by the Management Board and the shareholders. ASSE accepted Leicester’s exceptional offer, especially given the uncertain economic context caused by the health crisis.
“In addition, even if it presented, for the 2019-2020 financial year and for the tenth consecutive year, a positive financial result, the club sees for the moment its room for manoeuver considerably reduced by the consequent commitments made in as part of his previous sports project, in 2018, 2019 and until the beginning of summer 2020.
“Trained at the club and winner of the Gambardella Cup 2019, Wesley Fofana revealed himself last season, under the direction of Claude Puel. It is indeed with the General Manager of ASSE, appointed head of the Greens in October 2019, that he has made spectacular progress, thus establishing himself at the highest level.
“Last season, Wesley Fofana played 14 matches in Ligue 1, six in the Coupe de France, including the final against PSG, two in the Coupe de la Ligue and two in the UEFA Europa League. At only 19 years old, he is now considered one of the greatest French talents of his generation.”
