Mesut Ozil has torn ligaments in his left knee, despite playing the full ninety minutes against Chelsea last weekend.
He joins Arteta, Ramsey, Walcott, Debuchy, Gnabry and Giroud on the injured list - why do we have the worst injury record of any Premier League team over the last 6 years at least?
Maybe it's just bad luck, but one has to wonder whether training methods have any bearing on the situation.
Meanwhile Ozil should use his time on the sidelines to reflect upon why his performances this season have been so underwhelming. He needs to come back looking like the 40 million pound player that he is.
