Laurent Koscielny injured during Arsenal’s Europa League tie against Atletico Madrid

Arsenal defender Laurent Koscielny was stretchered off after just 12 minutes of their Europa League semi-final second leg at Atletico Madrid.

The 32-year-old lost his footing while moving towards Atletico forward Diego Costa off the ball and was in obvious distress as he clutched his lower leg.

The injury forced Arsenal into a change, with Calum Chambers replacing the France defender.

The France camp will be concerned about Koscielny, as they look towards a World Cup campaign which gets underway against Australia on June 16.
