Costa, Gabriel, Chelsea and Arsenal charged by FA

Chelsea striker Diego Costa has been charged with violent conduct by the Football Association after an incident with Arsenal's Laurent Koscielny which was caught on video.

The FA has also charged Arsenal defender Gabriel with improper conduct for his behaviour after being sent off, and both Chelsea and Arsenal for failing to control their players.

Arsenal manager Arsene Wenger said Costa should have been sent off after grappling with Laurent Koscielny, pushing the defender in the face with his hands before catching him with a flailing arm, in the first half of Chelsea's 2-0 win at Stamford Bridge - the incident was not spotted by referee Mike Dean.

The FA said in a statement: "Diego Costa has been charged for an alleged act of violent conduct which was not seen by the match officials but caught on video.

"The Chelsea forward was involved in an incident with Arsenal's Laurent Koscielny in the 43rd minute of the game. He has until 6pm tomorrow (Tuesday) to reply.

"Off the ball incidents which are not seen at the time by the match officials are referred to a panel of three former elite referees.

"Each referee panel member will review the video footage independently of one another to determine whether they consider it a sending-off offence. For retrospective action to be taken, and an FA charge to follow, the decision by the panel must be unanimous.

"Arsenal defender Gabriel has been charged with improper conduct for his behaviour following his dismissal, whilst team-mate Santi Cazorla has been warned for his behaviour following his sending off.

"Finally, both clubs have been charged for failing to control their players under FA Rule E20. Both clubs and Gabriel have until 6pm on Thursday (24 September) to reply."

Arsenal said they would appeal for both wrongful dismissal in relation to Gabriel and the length of his ban.

A statement read: "The club can confirm that it is appealing wrongful dismissal and the three-match ban given to Gabriel."

Jose Mourinho was seething when Costa was retrospectively sanctioned in February for treading on Liverpool's Emre Can, part of what the Chelsea boss perceived as a "campaign" against his side which included a Sky Sports montage entitled 'Costa's Crimes'.
