Real Madrid's German international Mesut Özil has reported the owner of a Twitter account for racial abuse, after the player was accused of not being German, according to the Bild newspaper.

The player's lawyer - Sascha Beumer – decided to take legal action after an unknown Twitter user posted messages using a private account during the Denmark-Germany game, stating that the player was not German and criticising his surname – which is of Muslim descent.

"Özil isn't German! A piece of paper doesn't change your origins", were the unknown user’s words in their first message, then adding that nobody with a non-German name should play in the German team.

Soon after, amid the protests - both online and offline -, Twitter decided to block the user's account from where the racist comments came from.

The Real Madrid player's father and agent - Mustafa Özil – totally agreed with his son's decision to report the incident: "it's important to say that you can't get away with saying things like that. This person has overstepped the mark".

Özil – who has played in all three of Germany's games so far in the 2012 Euros – was born in Gelsenkirchen (West Germany), while his parents come from Turkey. The Real Madrid player has always defended his German status.
