Arsenal manager Arsene Wenger has revealed the freak injury Mesut Ozil picked up against Chelsea was merely from passing the ball with the outside of his left foot. Ozil faces around two months of rehabilitation after scans on international duty with Germany discovered a 'partial rupture of the outer band of the left knee joint' which he suffered during the Gunners clash at Stamford Bridge. Wenger said on the injury: '(Do) you know how Ozil did the injury? Passing the ball with the outside of his left foot. He must have done that a million times.
