Arsenal have been handed a double boost with the news Laurent Koscielny and Johan Djourou have returned to training.
The central defensive pair have missed the last two games against Olympiakos and Tottenham through injury, meaning midfielder Alex Song has been forced to fill in at the back.
The pair are currently away on international duty with France and Switzerland respectively and Gunners boss Arsene Wenger will be hoping they return to the Emirates unscathed.
French defender Sebastien Squillaci is also back to fitness after failing to figure so far this term.
The news is a boost for Arsene Wenger as he prepares his side for the clash with Sunderland this weekend.
