The full-back joined the Gunners from Newcastle United in the summer of 2014 for a fee of £12 million but has lost his place in the starting line-up to Hector Bellerin.
His lack of appearances has led to his exclusion from the French national for the next round of fixtures against Armenia and Denmark.

With the European Championships in his home nation next summer he can not afford to be on the bench in north London.
A shoulder injury forced him to miss four months of the previous campaign and allowed academy graduate Bellerin to cement his position as first-choice right-back.
Debuchy considered leaving the Emirates over the summer but decided to remain at the club and fight for his place.
Having been France's starting right-back during the World Cup, it is a sign of the times for the defender that he has been dropped in favour of Bacary Sagna and Christophe Jallet.
The 30-year-old has been limited to three appearances in all competitions for Arsenal this season and has hardly covered himself in glory when given the opportunity.
His performance in the 2-1 Champions League defeat to Dinamo Zagreb was the perfect example of someone low on confidence and his positioning for Josip Pivaric's opening goal was woeful.
It seems Bellerin will only continue to strengthen his hold on the full-back spot as he continues to mature and it may be time for the French international to call an end to his short Gunners career.
For the good of his international hopes, there may be no other choice.
