Arsenal boss Arsene Wenger concedes Mesut Ozil is out of their clash with Chelsea.
Ozil was ruled out of Arsenal's trip to West Brom in the Premier League on New Year's Eve with a knee injury.
Gunners boss Arsene Wenger, who drafted in Alex Iwobi to replace Ozil for the game at the Hawthorns, said it's unlikely that the German will face Chelsea.
Asked whether the 29-year-old would be fit for the clash with the Blues, Wenger said: "Little chance, yes. From what I've heard."
