Arsenal are set to assess the fitness of central defender Laurent Koscielny, ahead of their match with Stoke City this weekend.
The defender has been struggling with a muscle injury in his lower back, and was left on the bench in France's 2-1 friendly win against Serbia.
Koscielny has been struggling with the psoas muscle injury for some time. The 29-year-old was forced to sit out the Gunners' draw with Liverpool, before returning for the win at Newcastle United.

However, the Gunners are concerned that the centre-back has aggravated the injury while away on international duty, according to the Mail.
The Emirates club will be hoping their defender can recover in time for the home match against the Potters, as they go in search of their first home win this season.
Despite keeping a clean sheet in the 0-0 draw with Liverpool, Arsenal looked considerably shaky at the back, and Calum Chambers, in particular, looked very nervous.
Koscielny's return for the trip to St. James' Park, brought an air of assurance to the Gunners' defence, as he formed a strong understanding with Gabriel Paulista, in the absence of Per Mertesacker.
After initially struggling to adapt to life in the Premier League, the former-Lorient man has become an ever-present figure in the heart of Arsenal's defence, in recent years.
The France international has made 206 appearances for the North London club, since joining in 2010, and his partnership with Mertesacker last season contributed to Arsenal boasting one of the best defensive records in the division.
Arsene Wenger's men can not afford anymore slip-ups so early into the new campaign and will be hoping to have one, if not both, of their central defenders fit, as they look to stay within touching distance of early leaders Manchester City.
