Manchester City defender Bacary Sagna may have bitten more than he can chew following a cryptic post on his instagram page. The message which read “10 against 12.. but still fighting and winning as a team″ after City’s 2-1 victory against Burnley on Monday is seemingly accusing referee of cheating. The Football Association (FA) has however asked him to explain the deleted post.

He has until 17:00 GMT on Friday to respond to the query.
