Carneiro left her position at Chelsea after she was given a public dressing-down by Mourinho for going on to the field, along with fellow club doctor Jon Fearn, to treat Eden Hazard in a match against Swansea on the opening weekend of the season.
At the time, Mourinho said: “I wasn't happy with my medical staff because even if you are a medical doctor or secretary on the bench, you have to understand the game.
“If you go to the pitch to assist a player, then you must be sure that a player has a serious problem. I was sure that Eden didn't have a serious problem. He had a knock and was very tired.
“My medical department left me with eight fit outfield players in a counter attack after a set piece and we were worried we didn't have enough players left.”
Carneiro is understood to have further angered Mourinho when in the immediate aftermath of the incident, she took to Facebook to express her thanks for the “overwhelming support” she received.
Mourinho, who has since been sacked, was cleared of the accusation - made by a member of the public - that he had shouted s3xist abuse at Carneiro by the Football Association, although the doctor was angry with the FA for not interviewing her.
She said: "I was surprised to learn that the FA was allegedly investigating the incident of 8th of August via the press.
"I was at no stage requested by the FA to make a statement. I wonder whether this might be the only formal investigation in this country where the evidence of the individuals involved in the incident was not considered relevant.
"Choosing to ignore some of the evidence will surely influence the outcome of the findings.
"Last season I had a similar experience at a game at West Ham FC, where I was subject to verbal abuse. Following complaints by the public, the FA produced a communication to the press saying there had been no s3xist chanting during this game.
"At no time was I approached for a statement despite the fact that vile, unacceptable, s3xually explicit abuse was clearly heard.
"It is incidents such as these and the lack of support from the football authorities that make it so difficult for women in the game."
