The Chelsea manager was alleged to have use the word, which translates as 'bitch', in a confrontation with Riley at half-time in the FA Cup quarter-final draw with Tottenham yesterday.

Riley did not mention any incident in his report however and he told the FA there was nothing to pursue further.

An FA spokesman said: "We have spoken to the referee who has clarified that there is no issue for us to pursue."

Mourinho denied he intended to offend the match official.

The Chelsea manager said: "If you listen to me speaking I say the kind of word you mention 10 times in every 15 words.

"If you have a microphone on the dugout, I say that during the game 20 times, easy. The word can be abusive if you understand it as an abusive word.

"I tell the word to my players when I am not happy. I say it 50 times in a game, 50 times in training and I don't want to be offensive.

"I can be emotional, but I am polite. I never want to be offensive with somebody."
