Manchester City defender Bacary Sagna has been charged for a "10 against 12" comment posted on Instagram after his side's 2-1 win over Burnley.
City were reduced to 10 men in the 32nd minute of the match on 2 January when referee Lee Mason sent off Fernandinho.
The Football Association allege that the post, which was later deleted, is "improper conduct in that it questioned the integrity of the match official".
The Frenchman, 33, has until 18:00 GMT on Friday to respond to the charge.
Sagna has played 14 times for the club in all competitions this season.
