Lyon have reached an agreement with Angers over the transfer of former Arsenal youngster Jeff Reine-Adelaide.
The transfer, worth a reported €25 million (£23m/$28m), is subject to a medical, while the Gunners also have first refusal on the midfielder.
Unai Emery's side are unlikely to bring him back to the Premier League, however, having signed the likes of Dani Ceballos on loan, Kieran Tierney from Celtic and Nicolas Pepe in a club-record deal this summer.
The 21-year-old left north London last summer after being told he was surplus to requirements by Emery, and went on to feature in 35 of Angers' 38 Ligue 1 matches in 2018-19.
His three goals and three assists helped the club to 13th place, while the France U-21 international also scored the first goal in Saturday's 3-1 league win over Bordeaux.
Reine-Adelaide joined Arsenal in 2015 after progressing through the Lens youth system, but he was loaned out to Angers in January 2018 after making just eight senior appearances in three years at the club.
The Frenchman then made his move permanent last summer, and has since been called up to France's U-21 set-up.
