Jose Mourinho's stadium ban for Saturday's match at Stoke was imposed after the Chelsea boss unleashed an expletive-laden half-time attack on referee Jonathan Moss and then refused to leave the officials' dressing room at West Ham's Upton Park.
The Football Association on Friday released the written reasons for the case which Mourinho opted not to contest, instead missing Saturday's Premier League encounter at Stoke's Britannia Stadium.
Referee Moss' testimony from half-time of the October FA reveal re24 clash between West Ham and Chelsea was key, with Mourinho furious after Nemanja Matic had been sent-off for two bookable offences and the visitors denied two goals, one due to goal-line technology and the other due to offside.
"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.
"Rather than publically (sic) speak to him I asked him to step into the entrance of my dressing room escorted by Simon Sutton, the West Ham United security manager.
"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."
