Arsenal midfielder Mesut Ozil will miss Germany‘s friendly against Saudi Arabia on Friday because of a knee injury, the German Football Association has confirmed.

Ozil, 29, picked up the problem during Saturday’s 2-1 defeat against Austria, and has been reported to be doubtful for Germany’s opening match of the World Cup on June 17 against Mexico in Moscow.

A statement on the German FA’s official Twitter feed read: “As a precaution, @MesutOzil1088 didn’t take part in final training today, completing running exercises instead. He is out of #GERKSA with a minor bruise to his left knee.”
