The Football Association has revealed that Chelsea manager Jose Mourinho unleashed a foul-mouthed rant at referee Jonathan Moss before being sent to the stands in last month's defeat to West Ham United.

The English governing body has released the written reasons for Mourinho's one-match stadium ban, which he has opted not to appeal.

In Moss's report after the game, which ended in a 2-1 defeat for Chelsea at Upton Park, the match official wrote: "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.

"Rather than publicly 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 fucking referees are weak. Wenger is right about you. You are fucking weak'. I advised Mr Mourinho not to take his position in the technical area for the second half due to his actions."

The Independent Regulatory Commission decided to take Mourinho's previous punishments into account when issuing him with a stadium ban and £40,000 fine.
