The Blues fell behind after Mauro Zarate’s 17th-minute opener, and while they equalised through Gary Cahill on 56 minutes, they were ultimately defeated when Andy Carroll bagged the winner on 79 minutes.
By this point, Mourinho had been sent to the stands after ranting at the refereeing team. The Portuguese coach has regularly shown the strain of the Blues’ testing start to the Premier League campaign, and the reigning champions remain off the pace in the top flight.
That loss to the Hammers was their fifth of the season, and was followed up by elimination at the hands of Stoke City in the Capital One Cup and Liverpool in the Premier League last weekend.
As such, every game has become a must-win affair for the Pensioners, with an EPL fixture against Stoke to come this weekend.
The Blues will be without Mourinho for this fixture, with the coach set to serve a stadium ban following his expletive-laden tirade aimed at referee Neil Moss, presented in full here:
“When myself and my colleagues left the field of play at half time, as we entered the tunnel area to get to our dressing room, Mr. Mourinho the Chelsea manager was waiting for us clearly agitated and began aggressively asking about first half decisions,” Moss says in the written reasons.
“Mr Mourinho asked me about a tackle, an offside and a goal line clearance. I gave him brief answers to his questions. After this I asked him to leave the dressing room area.
“He refused. I asked him again. After he refused again I asked Mr Sutton to escort him from the room. At this point Mr Mourinho became very aggressive and animated.
“He shouted that you ******* referees are weak… (Arsenal manager Arsene) Wenger is right about you… you are ******* weak.
“I advised Mr Mourinho not to take his position in the technical area for the second half due to his actions.”
