Mesut Ozil is one of six first-team players to return to full training ahead of Arsenal's trip to West Ham in the Premier League on Saturday.
Ozil has not featured for the Gunners since their 1-1 draw with Brighton and Hove Albion on Boxing Day, the Germany international subbed at half-time with a knee injury.
After missing Arsenal's last three matches, Ozil is back in contention to face the Hammers after taking part in Unai Emery's preparations on Wednesday.
His return is a welcome boost for Emery, who has seen his squad – particularly the defence – plagued by injuries in recent weeks, problems that appear to be easing.
