Arsenal have been dealt a huge injury blow after it was confirmed that Mesut Ozil has been ruled out of action with a knee injury.
Ozil had been away with the German national team ahead of their Euro 2016 qualifiers against Poland and Ireland, but he is now expected to be out of action until 2015.
The German football federation today confirmed that the 25-year-old had suffered a ligament tear in his left knee. A statement read: "The 25-year-old complained about discomfort in his knee on Tuesday when he arrived in Frankfurt.
"Having been examined by team doctor Dr. Hans-Wilhelm Müller-Wohlfahrt today in Munich, it was discovered that he has a partial lateral collateral ligament tear in his left knee. Mesut Özil is expected to be out for ten to twelve weeks."
Ozil managed 90 minutes for Arsenal in their 2-0 defeat against Chelsea at Stamford Bridge on Sunday, but an MRI scan in Germany revealed the full extent of his injury.
Arsenal's own statement confirmed the injury, but refused to put a timeframe on his absence.
It read: "Ozil complained of a sore left knee after the game and the club advised the German FA to run medical checks when he joined up with his international squad.
The club will make further assessments and it is too early to say how long Ozil may be out of action."
The German World Cup winger has been heavily criticised for his performances of late, but his absence will come as a massive blow for Arsenal who are struggling badly with injuries after a difficult start to the the new Premier League campaign. Boss Arsene Wenger is currently without no less than eight players, including Olivier Giroud, Theo Walcott, Aaron Ramsey, Mikel Arteta and Mathieu Debuchy.
So far Arsenal have won just two Premier League games this season, with their last victory coming against Aston Villa last month. That leaves them in 8th place in the Premier League with just 10 points from their first seven games.
Ozil has now returned to Arsenal where he will undergo further tests and treatment.
