Chelsea manager Jose Mourinho has been charged with misconduct for comments made about match officials after last month's draw at Southampton, the Football Association has announced.
Mourinho claimed there is a "clear campaign" by "people, pundits, commentators and coaches from other teams" against Chelsea and labelled the booking of Cesc Fabregas for diving at St Mary's on Dec. 28 a "scandal."
"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," a statement issued by the FA read.
Mourinho faces possible disciplinary action, though he has until Tuesday to respond to the charge.
Diego Costa and Willian were booked for simulation against Hull on Dec. 13, prompting Steve Bruce to compare a Gary Cahill dive as "like something out of Swan Lake."
The London club faced renewed scrutiny on Boxing Day when Branislav Ivanovic appeared to take a tumble against West Ham, the type of incident Mourinho believes is being unjustly scrutinised to Chelsea's detriment.
Fabregas looked to have won a penalty early in the second half against Southampton after being caught by Matt Targett, but referee Anthony Taylor instead deemed it a dive and booked the furious Spanish midfielder.
Asked if recent incidents involving Cahill and Ivanovic had been influential, Mourinho said: "Of course. That's a campaign, that's a clear campaign. People, pundits, commentators, coaches from other teams -- they react with Chelsea in a way they don't react to other teams.
"They put lots of pressure on the referee and the referee makes a mistake like this. We lose two points, Fabregas earns a yellow card."
Separately, Mourinnho been issued with a formal warning for saying last month's match at Stoke required a "good, experienced referee" to spot aggressiveness from the opponent. Neil Swarbrick oversaw that match.
"Having sought Mourinho's observations on this matter, the FA has decided not to bring a disciplinary charge and has instead issued a formal warning," the FA statement read. "The FA prohibit participants from making any pre-match media comments including comments of a positive nature concerning the appointed match officials for a particular fixture.
"Whether the official is identifiable by name or by implication, these are deemed to amount to improper conduct in breach of FA Rule E3."
The Portuguese was scheduled to face the media on Friday to preview Saturday's Premier League clash with Newcastle, but shortly after the FA announced the charge Chelsea revealed his place was being taken by assistant manager Steve Holland.
