The Football Association has reportedly asked Manchester City full-back Bacary Sagna to explain his reasons behind posting a message on social media appearing to criticise referee Lee Mason.
The 33-year-old wrote, "10 against 12... but still fighting and winning as a team," on Instagram following City's 2-1 win over Burnley on Monday afternoon.
Pep Guardiola's side took maximum points, but they had to do so with 10 men after Mason sent off Fernandinho half an hour into the match, while City also argued that Burnley's goal should have been ruled out following a foul on goalkeeper Claudio Bravo.
According to PA, the FA wants to learn if Sagna was questioning the referee's integrity in his post, which was later edited to say: "Still fighting and winning as a team."
The full-back has until 5pm on Friday to respond to the English governing body.
