Just because you were born in Germany, that doesn't make you from that nationality.
Mesut Ozil refuses to sing German anthem, he even curses in Turkish when he misses goals in Real Madrid
His father and his mother don't even speak German much. How is he German? I dont understand it. He admits he has Turkish blood and
refuse to sing any other national anthem. He plays for Germany for his career. Same as Nuri Sahin, but on top of that, he plays for Turkey.
