The former Chelsea manager Jose Mourinho has admitted swearing at Eva Carneiro during an employment tribunal over the doctor's dismissal.
Dr Carneiro is claiming she was personally discriminated against by Mourinho in the build-up to her alleged constructive dismissal by the club.
The manager is expected to give evidence in person at a hearing in London on Tuesday.
And in a written statement to the panel, Mourinho conceded using the Portuguese phrase "filho da puta", meaning "son of a b**** or w****", as Dr Carneiro ran onto the pitch to treat Eden Hazard during a match against Swansea on 8 August last year.
Dr Carneiro's lawyer, Mary O'Rourke QC, told the panel Mourinho used the phrase "filha da puta", meaning "daughter of a b**** or w****", which the doctor says she heard "clearly from behind her" as she ran onto the pitch.
She said: "He uses the word 'filha' because he is abusing a woman."
But in his statement, Mourinho said he had been swearing in a general way throughout the game and denied any sexism.
"Filho da puta is a phrase I often use, all of the players know it," he said. "There is no sexist connotation in the use of the phrase - it is just like saying 'f*** off'.
"In the world of football, a lot of swear words are used."
The tribunal is anticipated to be heard over seven to 10 days, after the parties failed to agree a settlement which would have prevented a public hearing.
Dr Carneiro was dropped as Chelsea's first-team doctor last year after then-manager Mourinho angrily berated her and physio Jon Fearn for going on to the pitch.
Their action meant that Chelsea were temporarily down to nine men, and afterwards Mourinho called Dr Carneiro and Mr Fearn "impulsive and naive".
Dr Carneiro did not appear on the bench again for first-team duties and later parted company with the club.
The hearing continues.
