The France international has slipped completely out of favour at the Emirates this season and appreciates that the time has come to move on.
The 32 year old told Vermatin.com: "With (Laurent) Koscielny, (Per) Mertesacker and (Johan) Djourou, the competition is fierce.
"I played in the Champions League with Olympiakos. I have played five times for the reserves and I always train seriously.
"My relationship with Arsene Wenger is good. I remain as professional as possible.
"I will be out of contract at the end of the season. As things stand, I will leave, perhaps during the January transfer window or else in June."
He added: "Of course, playing in my home region of Provence-Alpes-Cote d'Azur is something that interests me.
"Marseille, Nice, Monaco, Bastia and Ajaccio are clubs who speak to me. I am 32, and I still have two or three good seasons left.
"I will make my choice depending on the opportunities that arrive."
