Dr Carneiro is claiming constructive dismissal against the former Premier League champions
Chelsea's former first-team doctor, Eva Carneiro, apparently turned down an offer of £1.2m ahead of an employment tribunal case she has now begun against the club.
Dr Carneiro, 42, is claiming constructive dismissal against the former Premier League champions.
She is also taking separate action against former manager Jose Mourinho for alleged victimisation and discrimination.
Dr Carneiro's lawyer, Mary O'Rourke QC, told the hearing in Croydon, south London, she would probably want to question Mourinho for at least a day.
In documents submitted on behalf of Chelsea and Mourinho, it was stated that Dr Carneiro had been "made an open offer of £1.2m to settle her claims".
The club claimed that contemporaneous documents showed that Dr Carneiro did not consider Mourinho's actions, during a match last August, to be discriminatory.
The skeleton argument said: "The purpose of the discrimination claim was to lift the statutory cap, in order to justify the claimant's extravagant compensation claim."
On the tribunal's first day, the panel heard an extract from Mourinho's statement in which he concedes that he used the Portuguese term "filho da puta", meaning "son of a bitch or whore", but he had been using it throughout the match.
"Filho da puta is a phrase I often use. All of the players know it" Mourinho 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."
But Dr Carneiro alleges that Mourinho used a slightly different term, "Filha da puta", meaning "daughter of a bitch or whore".
"He uses the word 'filha' because he is abusing a woman," Ms O'Rourke said.
She added that Dr Carneiro heard the term "clearly from behind her" as she ran on to the grass.
The incident which led to Dr Carneiro leaving Chelsea happened on the first day of the 2015-16 Premier League season on August 8.
During a match against Swansea at Stamford Bridge, she and physio Jon Fearn were berated by Mourinho for going on to the pitch to treat midfielder Eden Hazard.
It meant that Chelsea were temporarily down to nine men. Afterwards, Mourinho called Dr Carneiro and Mr Fearn "impulsive and naive".
Dr Carneiro did not appear on the bench again and later left the club.
She is expected to give evidence for at least two and a half days. The tribunal was adjourned until Tuesday.
