The United manager had been the subject of intense speculation in the build-up to the stirring late 3-2 victory, with a report in The Mirror claiming he would be sacked regardless of the result.
Second-half goals from Juan Mata, Anthony Martial and Alexis Sanchez ensured United avoided a fourth Premier League loss of the season and Mourinho spoke afterwards about the impact of “the pressure of man-hunting” on his players.
But it is his touchline comments that have brought the under-pressure manager to the FA’s attention.
