Manchester City defender Bacary Sagna could face retrospective action from the FA after an outburst on social media following his side's 2-1 win over Burnley.
City midfielder Fernandinho was sent off for a two-footed lunge on Burnley's Johan Gudmundsson, with many believing the decision to be the correct one from referee Lee Mason.
That was not the perspective of City's Sagna, however, who took to Instagram to criticise the officiating at the Etihad Stadium.
Sagna has since altered the post so there is no reference to Mason's decision to dismiss Fernandinho. The 33-year-old could still be in hot water, however, with his comments in line with a breach of the FA's E3 rule, which states (as quoted by the Daily Mail):
"Comments about match officials which imply bias, attack the officials' integrity' can be considered in breach of the rule."
Should the FA decide Sagna's post questioned the referee's integrity then he could be punished.
The sending off of Fernandinho mattered little in the end, as Manchester City ran out 2-1 winners thanks to goals from Gael Clichy and Sergio Aguero, with Ben Mee's later strike proving to be little more than a consolation.
City reclaimed their place in the top four thanks to the win, with Arsenal travelling to Bournemouth on Tuesday before Tottenham take on Chelsea on Wednesday.
