The FA has charged Martin Skrtel for his stamp on David De Gea at the end of Manchester United's win on Sunday over Liverpool.

Neither referee Martin Atkinson nor his assistants spotted the incident at the time, allowing the FA to take retrospective action based on television footage.

An FA statement read: "In Premier League matches, if an incident has not been seen by the match officials, a three-man panel of former elite officials will be asked by the FA to review the footage independently of each other.

"They will then advise what, if any action, they believe the match referee should have taken had it been witnessed at the time.

"For an FA charge to follow, all three panel members must agree it is a sending-off offence.

"In this instance, the decision by the panel was unanimous."

Skrtel could receive a three-match ban.
