Saint-Etienne coach Claude Puel is hopeful William Saliba can remain with the club for the Coupe de France final before he has to link up with Arsenal.
The centre-back signed for Arsenal on a long-term contract last July but immediately returned to Saint-Etienne on a season-long loan.
Les Verts progressed to the Coupe de France final before the French football season was halted by the coronavirus pandemic.
While Ligue 1 was decided on a points-per-game basis, with Saint-Etienne consigned to a lowly 17th-placed finish, they can still qualify for the Europa League by beating Paris Saint-Germain in the Coupe de France final.
That contest is provisionally scheduled to take place on July 24, but Saliba's loan is due to end on June 30.
"William is at the end of his contract at the end of the month," Puel said in a media conference.
"He takes great pleasure in training with his team.
"We will see what can be done to keep him a little longer with us."
