Chelsea manager Jose Mourinho has been charged with improper conduct by the Football Association.
Mourinho claimed Manchester United boss Sir Alex Ferguson influenced referee Neale Barry in the Carling Cup semi-final first leg with Chelsea.
Mourinho, who has until 14 February to respond, told Chelsea TV: “In the second half it was whistle and whistle, fault and fault, cheat and cheat”.
But defender John Terry will not be charged after he backed Mourinho.
Terry said at the time: “With most refs and being captain, you can maybe have a word, but he just wasn’t willing to listen which was disappointing.”
In a statement, the FA said it had “reviewed the content and context of these comments, (and) decided that it is not appropriate to take formal disciplinary action.”
