Ozil was fiercely criticised as Germany crashed out of the World Cup at the group stage, while posing for a photo with Turkey president Recep Tayyip Erdogan ahead of the tournament led to a backlash in sections of the German media and support.
The 29-year-old, who is of mixed German and Turkish heritage, announced on Sunday evening that he was retiring from international duty, claiming racial discrimination from German football officials.
Ozil feels he was happy.
