Mesut Ozil threatens to add to Arsenal's worryingly long injury-list after it was announced by the German Football Association (DFB) he would be undergoing tests on a knee complaint.

The midfielder joined up with the national team prior to their Euro 2016 qualifiers against Poland on Saturday and the Republic of Ireland next Tuesday, but has been unable to train with the World Cup winners.

Ozil played a full 90 minutes in Arsenal's defeat to Chelsea on Sunday and there were no suggestions of an injury after the match.

However, according to the DFB he arrived for international duty with the complaint.

The governing body said on its official website: "The Arsenal player had come with complaints in the left knee when he met up with the German team in Frankfurt and on Wednesday morning, he travelled to Munich to undergo an MRI examination."

The news will be a worry for Gunners boss Arsene Wenger, who is facing something of a midfield crisis with Aaron Ramsey, Serge Gnabry and Mikel Arteta already on the sidelines. Theo Walcott also remains unavailable whilst in other departments, Olivier Giroud, Yaya Sanogo and Mathieu Debuchy are unavailable.
