Chelsea manager Jose Mourinho has been charged with misconduct for his actions towards match officials at half-time of Saturday's Premier League match at West Ham, the Football Association announced on Monday.
Chelsea first-team coach Silvino Louro has also been charged with misconduct, and both clubs have been charged with failing to control their players.
Mourinho was sent to the stands by referee Jonathan Moss during half-time of Chelsea's 2-1 defeat at West Ham. Andy Carroll's second-half header condemned the Blues to a fifth defeat in 10 matches as the ailing champions imploded at Upton Park.
Having seen Nemanja Matic red-carded on the stroke of half-time, and Louro dismissed from the dugout, the embattled Blues boss did not emerge from the tunnel after the interval.
A statement from the FA read: "Jose Mourinho has been charged with misconduct in relation to his language and/or behaviour towards the match officials in or around the dressing room area at half-time.
"Chelsea coach Silvino Louro has also been charged with misconduct in relation to his behaviour which led to his 45th minute dismissal from the technical area," the FA statement added.
"West Ham have been charged for failing to control their players in the 44th minute of the game and Chelsea have also been charged with the same offence for an alleged breach in the 45th minute of the game.
"All parties have until 6pm on Thursday [Oct. 29, 2015] to reply."
Mourinho's position as Chelsea boss is under scrutiny after a fifth loss from 10 Premier League games this term, the latest after a first-half implosion.
The charges are likely to ensure Mourinho's relationship with the FA deteriorates further. He is contesting the £50,000 fine and suspended one-match stadium ban levied for comments about referee Robert Madley following the Oct. 3 loss to Southampton.
He branded the sanctions a "disgrace" and "absolutely astonishing," adding, "I am happy that I don't have an electronic tag. I think it's not far from [that]".
Mourinho, whose suspended stadium ban relates specifically to media comments, perceives inconsistencies in the FA's disciplinary process and called for his relationship with the governing body to be examined. He has publicly highlighted Arsene Wenger avoiding sanctions for pushing him in the technical area in October 2014 and for calling referee Mike Dean "weak and naive" following Arsenal's loss at Stamford Bridge last month.
The events at Upton Park prompted the latest in a long line of disciplinary events involving Mourinho during his second spell as Chelsea boss.
Chelsea were already hit with an automatic fine of £25,000 for six or more bookings in the contest, while Serbia midfielder Matic will serve a one-match ban, missing the Capital One Cup fourth-round tie at Stoke on Tuesday night.
After Mauro Zarate's opening goal, Chelsea felt a succession of decisions went against them. Kurt Zouma had a header cleared off the line, with only goalline technology proving no goal had been scored, before Matic was booked for hauling down Cheikhou Kouyate as he led the counter-attack.
Next, Cesc Fabregas thought he had scored from Willian's pass, only to be adjudged offside. It was a decision which infuriated Mourinho, who made his displeasure known to the fourth official and assistant referee.
Matic was then shown a second yellow card for a touchline foul on Diafra Sakho. It was an unnecessary challenge in the circumstances as defenders were covering.
Louro was sent off and, when Mourinho did not emerge on the touchline for the second half -- instead being found in the West Ham directors' box -- it became apparent that he, too, had been dismissed at the interval.
Mourinho afterwards did not speak to the media, in breach of Premier League regulations.
