Mesut Ozil is back in the Arsenal squad, but he is only on the bench.
The German star Ozil has not made the initial alignment to face Chelsea in the Emirates, but has been given a kind of reprieve.
Ozil posted an Instagram post on Friday to show he was fit, as he was last week against West Ham, but he has not started a game since Boxing Day when he was replaced at Brighton.
The long-term future of Ozil is in doubt, since the midfielder of £ 350,000 a week has fallen under the hierarchical order of Unai Emery.
And despite Arsenal's poor run of results, Emery still has not put Ozil back in his starting lineup for the huge London Derby.
