The Football Association have charged Chelsea manager Jose Mourinho with improper conduct.
The Portuguese tactician was critical of referee Anthony Taylor and his match officials after the 1-1 draw with Southampton on December 28 and has been handed a charge by the FA.
"It is alleged his remarks constitute improper conduct in that they allege and/or imply bias on the part of a referee or referees and/or bring the game into disrepute," read a statement released by the FA.
In regards to what Mourinho felt was a missed penalty in the draw with the Saints, which actually saw Cesc Fabregas booked for diving, the Blues boss said: "There is a campaign against Chelsea. I don't know why there is this campaign and I do not care.
"Everybody knows it was a penalty. The referee made a mistake, people make mistakes and he made a big mistake."
Additionally, Mourinho has been warned about his future conduct stemming from comments he made prior to the December 19 meeting with Stoke City.
"Having sought his observations on this matter, decided not to bring a disciplinary charge and instead issued him with a formal warning," the FA statement added.
