Arsenal face an untimely injury crisis as they prepare to open their Champions League campaign for another season with one of the toughest trips in Europe on Tuesday night. The Gunners will come up against Borussia Dortmund and the famous 'Yellow Wall' at the Westfalenstadion and will have to do so without a number of key personnel in defence. Summer buy Mathieu Debuchy will be out for two months after damaging ankle ligaments against Manchester City and Nacho Monreal did not make the trip to Germany. Calum Chambers is suffering from tonsilitis and is rated '50-50', leaving Arsene Wenger with a patched-up defence.
