Arsenal midfielder Mesut Ozil has caused a stir among Chinese football fans for recent posts on social media.
On Instagram, the 31-year-old playmaker made clear his opposition to the treatment of the Muslim minority Uighur population in China's north-western region of Xinjiang.
It is alleged that they have for years been the subject of ethnic and religious persecution by the Chinese authorities.
Ozil, a practicing Muslim himself, accused the wider Muslim world of abandoning the Uighurs.
His stance has provoked a backlash among Chinese fans though - they argue that he should stick to football and stay out of politics.
Arsenal have distanced themselves from the player's comments.
