Laurent Koscielny's future at Arsenal is in doubt, with coach Unai Emery said to be keen on a major overhaul at the back.
Arsenal struggled last season in the defense quarter, leading to loss of key matches that eventually locked them out of Champions League football for next season.
It's now emerging that the Frenchman's future at the club is uncertain, with reports indicating he might be left to leave if the coach acquires the 'right' targets.
Koscielny has a year left on his contract with the club, and even though he would love to continue serving the team, the assurance of longterm future might convince him to ditch the side.
A host of European teams have been linked with the defender notably Inter Milan and Bayer Leverkusen, while Bordeaux and Rennes are among the French clubs interested in the 34-year-old.
Arsenal, however, will have to sell before buying any player at the back, with Shkodran Mustafi one other candidate that might be moved on.
Mustafi endured a season to forget at the club, as he was accused several times of costly mistakes which cost the team points.
The Gunners have been linked to some defenders, with Barcelona's Samuel Umtiti thought to be a top target.
The Frenchman has however indicated that he would love to continue playing in Spain, and a transfer might not happen easily.
