The Germany-born midfielder is the son of Iranian parents and appears to sympathise with Iran's political stance against Israel.

"Everybody knows I am a German-Iranian," he told the Bild newspaper. "This has political reasons."

However, German Football Association president Dr Theo Zwanziger is distressed by the 21-year-old's decision.

He said: "If we start delving into politics, then sport would be the big loser."

Germany under-21 coach Dieter Eilts has accepted the Wolfsburg midfielder's decision and has not called up any player to replace him.
