Arsenal defender Laurent Koscielny has returned to training after surgery on an ankle injury.

Koscielny sustained the issue during the second leg of last season's Europa League semi-final with Atletico Madrid, and the France international was ruled out of the World Cup.

The 32-year-old is expected to be sidelined for at least another two months, but the centre-back gave the Gunners a boost by making an appearance at the club's training ground.

Arsenal have missed Koscielny during the opening weeks of the Premier League campaign, with five goals being conceded in defeats to Manchester City and Chelsea.

Shkodran Mustafi, Sokratis Papastathopoulos, Rob Holding and Konstantinos Mavropanos are currently acting as Arsenal's options in the centre of defence.
