Arsenal star Mesut Ozil has come under fire from Lothar Matthaus, who has questioned his passion to play for Germany, according to Mirror Football.
"What displeases: His body language is negative," wrote Matthaus in his Bild column. "He is in the game without joy.
"I often have the feeling that on the pitch Ozil doesn’t feel comfortable in the DFB jersey, is not free - almost as if he does not want to play.
"There is no heart, no joy, and no passion. After the latest impression, it is not excluded for me that he withdraws from the national team after the World Cup."
Matthaus also added: "For a year or two, Ozil has played at a level that does not justify the free ticket of Jogi Loew.
"If things go well then Ozil plays well too. If things are going badly, it [a poor performance] will happen."
“I emphasise: I have no problem at all that Özil does not sing along with the anthem," added Matthaus. "This is up to each player, whether he has German, Turkish or African roots.
“But what I have observed after the anthem in Moscow, made me very angry: 10 German players have waved into the audience, given the fans a sign. Only Özil didn’t.
“This makes it obvious to me: Özil doesn’t understand why there are such great discussions in Germany about him.
"He’s unaware of what people in Germany expect from a national player. It would have been right to make a commitment to Germany after the error of the Erdogan photo, to open to the fans.”
