26-year-old Umtiti has been told to find a new club and is the last of the higher earners the Barcelona board hope to move on.
And his former club Lyon could offer him a return to Ligue 1 with talks initiated in recent hours.
Umtiti wants to revive his career before Euro 2021 and could return to Lyon on an initial loan deal.
His knee problems and salary make this a complicated transfer, but his camp are in contact with OL over a potential move.
Barcelona signed Umtiti from Lyon in 2016 for a fee of €25m, and he settled in well at Camp Nou.
However, injuries have led to the French international losing a yard of pace and Barca want to sell him.
The Catalan club could use Lyon’s interest in Umtiti to score a deal for Memphis Depay, one of Ronald Koeman’s targets.
