The head of the FA cannot believe that Fernando Torres got off scot free after raking his hand across Jan Vertonghen’s face.

The Chelsea striker was sent off during the Blues’ recent London derby draw with Spurs, but because the match officials saw only some aspects of his altercation with Vertonghen, retrospective punishment did not take place.

But the obvious nature of Torres’ crime has left FA chairman Greg Dyke red faced.

He thinks Torres should have been heavily sanctioned and has hinted that the FA will again have to revise its rules to ensure that players no longer slip through the cracks after misbehaving on the field of play.

"When millions of fans watching on TV can see an incident like this [Torres’ foul on Vertonghen] and the FA does not take action it is understandably baffling to everybody and this has to be addressed," Dyke said at the Leaders in Football conference.

"For the FA's disciplinary department to find itself in a position where it is not able to take action against an obvious scratch just can't be right.

"What this means is, despite the rules being changed in the summer, they clearly weren't changed enough.

"As FA chairman I don't like to be in a position where I cannot explain the rules when action should be taken when something is pretty obvious."
