Sergio Aguero faces an anxious wait to see if he will miss the Manchester derby through suspension.

The Manchester City star was caught on camera appearing to catch defender Winston Reid with his elbow during the 3-1 home win over West Ham on Sunday.

Should be charged Aguero would likely be handed a three-match ban which would see him miss the clash with rivals United on September 10.

But how will it be decided whether Aguero will be charged though, and what is the process behind it?

The Manchester Evening News take a closer look at what the FA guidelines are, according to a video they released at the start of last season.

Can the FA charge Aguero retrospectively?

"The FA has the power to take retrospective action for certain incidents that are not seen by the match officials , particularly where evidence is caught on camera.

"Action may also be taken where one of the match officials saw part of an incident, for example if an act of misconduct took that could not have been seen by the match official as their view was blocked.

What happens next?

"When an incident is brought to the FA's attention, the referee is asked whether they or any of the other officials saw the incident.

"If they confirm they did see the incident, then in most cases no further action is taken. However, if the officials confirm they did not see the incident then it becomes subject to further review .

Who will decide whether to ban Aguero?

"In the professional game, incidents are referred to a three-person expert panel of former referees who give their view of whether the incident merited a dismissal.

" If they all think it did, the case goes forward for consideration by a regulatory commission . The player will have the opportunity to put their side to the commission in writing, and provide any video footage of the incident that they want the commission to consider.

" If the commission agrees that the player committed a dismissal offence, the player will be suspended for the appropriate number of matches as if it had been seen at the time and dealt with by a dismissal.

"At other levels of the game, the procedure is the same except that the match referee - rather than the panel - is asked whether they would have dismissed the player had they seen the incident.

"All cases are heard before the player's next match."
