The Blues boss has been sanctioned for bringing the game into disrepute for his comments made towards referee Mike Dean after his side's 2-1 defeat at Stamford Bridge
Mourinho said he wanted to "congratulate" referee Mike Dean for his "unbelievable" performance at Stamford Bridge on April 19 after watching Fabio Borini grab a late winner from the penalty spot after Dean had adjudged Cesar Azpilicueta to have fouled Jozy Altidore.
The defeat put a serious dent in Chelsea's title hopes with Mourinho's assistant Rui Faria having to be restrained after being asked to leave the technical area during the defeat.
Mourinho denied the charge but has now been sanctioned for bringing the game into disrepute by the game's governing body.
"While the commission did not find that Mourinho’s post-match comments called into question the integrity of the referee appointed to the above fixture and/or the integrity of Mike Riley, general manager of the Professional Game Match Officials Limited, they did find that the comments brought the game into disrepute and the charge for improper conduct was found proven," read a statement on the FA's website.
"Meanwhile, Mourinho has lost his appeal against an Independent Regulatory Commission’s decision to fine him £8,000 in relation to Chelsea’s game against Aston Villa on on 15 March 2014.
"Mourinho denied a breach of FA Rule E3 in that his behaviour in re-entering the field of play and approaching the Match Referee in an attempt to speak to him, in or around the 90th minute of the game amounted to improper conduct.
"The charge was found proven by an Independent Regulatory Commission and that decision was upheld by an Appeal Panel on Thursday."
