Jose Mourinho has been fined 25,000 pounds and warned about his future conduct by the FA for comments the Portuguese coach made after Chelsea's 1-1 draw against Southampton in December.
Mourinho was charged after declaring that his side were victims of a "campaign" following a draw at St Mary's on Dec. 28.
Cesc Fabregas' appeals for a penalty were waved away by referee Anthony Taylor 55 minutes into the game, with the Blues midfielder instead booked for simulation.
Asked about the incident in his postmatch news conference, Mourinho said: "I think this is a result of something that looks like a campaign."
A statement on the FA's official website read: "Following an Independent Regulatory Commission hearing, Jose Mourinho has been fined 25,000 pounds after he was found to have breached FA Rules in relation to media comments.
"The Chelsea manager denied that comments he made after the game against Southampton on Dec. 28, 2014 constituted improper conduct in that they alleged and/or implied bias on the part of a referee or referees, and/or brought the game into disrepute.
"The Independent Regulatory Commission found the comments were a breach of FA Rule E3 in that they were improper and brought the game into disrepute. The Commission did not, however, find that the comments implied bias on the part of a referee or referees.
"Mr Mourinho, who had requested a non-personal hearing, was also warned as to his future conduct."
Following the draw against Southampton, Mourinho reflected on previous incidents when his players had been booked for diving by saying: "In other countries this is front-page news because it's an absolute scandal.
"In the first match [against Burnley], Diego [Costa] was booked when it should have been a penalty and a red card for their player. A few months later, we lose two points in a match when the penalty is there and Fabregas gets a yellow card. We have had bad yellow cards.
"After the game against West Ham [on Boxing Day], in a game that finished 2-0 and could have been four or five, Enner Valencia made a bad dive and all I hear at the end is an incident with Branislav Ivanovic. What is this?
"I do not make campaigns and this is not against me -- this is against Chelsea. Against Chelsea, yes. In the last couple of weeks, the two most important things in my matches in my opinion: Filipe Luis and Eden Hazard could be now in hospital with broken legs. And people speak about Gary Cahill [diving] against Hull City."
