Matteo Guendouzi is closing in on a move to Marseille, with William Saliba expected to follow him to the Stade Velodrome.
Arsenal have been locked in talks with the Ligue 1 outfit for several weeks over a deal for Guendouzi.
The midfielder has not played for the Gunners since June, 2020.
Agreement has now been reached for the 22-year-old, with Marseille hopeful of finalising a deal within the next week.
Guendouzi to join Marsille on loan
He will initially join Marseille on loan for the 2021-22 season.
But the deal includes an obligation to buy next summer.
In all, Arsenal will receive around £10m ($14m) for the France U-21 international.
Marseille will pay a loan fee of £850k for the coming season.
Then they will pay around £9m ($12m) to turn the move permanent in the summer of 2022.
Arsenal are hopeful of swiftly wrapping up a move for Anderlecht midfielder Albert Lokonga to replace Guendouzi.
