The action by the FA is related comments made by Mourinho as he walked off the Old Trafford pitch.
It is claimed Mourinho said ‘fodas filhos de puta’ which translates as ‘f*** off sons of b*****s’ in Portuguese.

The Manchester United boss also wagged his little finger at the camera as he walked down the touchline towards the tunnel.
Mourinho has until Friday at 6pm to respond and if he admits the charge, he could be suspended from the touchline for United’s Saturday lunchtime clash with Chelsea.
“It is alleged that his language at the end of the fixture, as captured by the broadcast footage, was abusive and/or insulting and/or improper.
“He has until 6pm on 19 October 2018 to respond to the charge.”
In November 2016, Mourinho was given a one-match touchline ban and fined £16,000 for kicking a water bottle during a 1-1 draw with West Ham.

And just a few weeks before, he was fined £58,000 and handed a one-match touchline ban after accepting two FA charges of misconduct.
The incident Mourinho has been charged with came after his side staged a second-half fightback to beat Newcastle 3-2.
And after the match, Mourinho lashed out at his critics and condemned a perceived “manhunt” against him.
He said: “I am 55 years old. It is the first time I see man-hunting. I can cope with it.
