The French youngster fell out with his manager last season, and is presently on loan at Marseille in Ligue 1.
The all action midfielder is enjoying a good season in France, leading to speculation he may earn a first team reprieve at Arsenal next season.
Arteta told reporters: "For right now, he's gone for the season. I think he's having a really good spell at Marseille, and it's part of the plan we made with him. He's continued with his development and we'll make a decision at the end of the year."
Asked if the Frenchman had played his last game for the club, he added/; "I think you cannot say that about a player that is owned by the club."
