Matteo Guendouzi has Marseille on loan from Arsenal.
But a clause in his contract, inserted by the Gunners, suggests the French midfielder will not be returning to north London.
Gunedouzi was a regular part of Unai Emery’s Arsenal squad and this continued when Mikel Arteta took the reigns.
But a number of issues involving the 22-year-old, including a row with the manager during a warm-weather training camp and his poor behaviour in a defeat by Brighton, in which he throttled Neal Maupay, saw him dropped.
Guendouzi was sent out on loan to Hertha Berlin last season and was expected to return to Arsenal this summer before he announced suddenly on social media that his time in north London had come to an end.

The midfielder, though, later deleted his posts on both Twitter and Instagram.
Guendouzi has now secured a loan move to Ligue 1 side Marseille, but is expected to stay longer than just the coming season.
Arsenal included an option-to-buy clause in the contract, suggesting Arteta still doesn’t see a future for Guendouzi at the Emirates.
The 22-year-old’s goodbye message took social media by surprise on Monday when wrote directly to the Arsenal fans.
“Thank you Arsenal. Thanks for everything!” he said.
“I discovered and learned so much during my time here. It would be impossible to list everything without forgetting one memory or word… but I will never forget any minute spent with the Gunners jersey.
“I will never forget the Emirates Stadium. I will never forget the fans. I won’t forget the city.
“I will never forget everything I’ve been through here. I will never forget that my only will was to defend with pride Arsenal colours.
“Thanks to all of those who believed in me during my time here, during the good and the bad moments. I can only wish the best to the club and its fans who deserve so much, trust me! Goodbye Arsenal, I will never forget you and will be a Gooner forever.”
