Arsenal have confirmed that defenders Laurent Koscielny, Johan Djourou and Sebastien Squillaci will all be back for Sunday’s home game, against Sunderland, in the English Premier League.

This will be a massive boost for manager Arsene Wenger who will be in a position to possibly rest Germany International Per Mertesacker and to also move Cameroon’s Alex Song back to his natural position as defensive midfielder although to be said is that the 24-year old was exceptional in the Arsenal defensive department.

Unfortunately, the Gunners will however not be able to use Belgium’s Thomas Vermaelen who, according to the Arsenal boss, needs “one or two more weeks” before making his long-awaited comeback with the 25-year old to certainly feature against Chelsea, away from home, on October 29.

Also out injured are right-back Bacary Sagna who will be out on the sidelines for approximately three months after undergoing surgery on a fractured fibula in his right ankle and midfielders Abou Diaby and Jack Wilshere, with the Englishman not back before January 2012.

Arsenal are currently 15th in the English Premier League table and cannot afford to drop any more points if they want to challenge for a Top Four finish.

On Sunday, the Gunners will host Nicklas Bendtner’s Sunderland for the day’s early kick-off and will then travel to France for their key Champions League game against Olympique Marseille, away from home.
