LONDON. — Arsenal defender Laurent Koscielny has returned to training to help ease Arsene Wenger’s central defensive concerns ahead of the season-opener against Crystal Palace.
The France international was substituted at half-time of Sunday’s comprehensive 3-0 Community Shield win over Manchester City with an Achilles problem.
But Koscielny is back in training and could still be available for tomorrow’s clash against Tony Pulis’ side.
Without Koscielny, Wenger would face something of a dilemma in central defence.
His only other established central defender, Per Mertesacker, just started pre-season training on Monday following Germany’s World Cup success.
Calum Chambers has played at centre back in all three of his pre-season appearances for the Gunners since his £16 million arrival from Southampton and looks set to feature in the heart of Arsenal’s defence on Saturday. — Mailonline.
