Embarrassing details of the row between Chelsea manager Jose Mourinho and sacked team doctor Eva Carneiro are likely to be aired in public after she and the club failed to reach a settlement yesterday.

Dr Carneiro, 42, was attacked by Mourinho for running on to the pitch to treat an injured player during Chelsea’s first game of the season last August. He later criticised her as ‘impulsive and naïve’.

She is now claiming unfair dismissal after leaving the club last September without a settlement and attended a preliminary hearing at London South Employment Tribunal in Croydon yesterday.

Mourinho’s public criticism of the sports doctor is believed to have played a significant part in the club’s decision to sack him last month.

He now faces further embarrassment, with text messages and emails sent by him and Miss Carneiro likely to be used as evidence during the tribunal.

Mourinho did not attend the hearing but could be ordered to do so when the full tribunal commences, facing a possible fine of £1,000 if he does not show up.

Dr Carneiro, who joined Chelsea in 2009 and became first team doctor in 2011, made no comment as she left after three hours at the hearing. Her lawyer, Mary O’Rourke QC, said there was no settlement but a date was fixed for the next hearing.

The date for the full tribunal is understood to be in June after the Barclays Premier League season ends.

On Wednesday, Carneiro refused to speak to the press before witness statements were dealt and documents disclosed, including emails and text messages from both before and after she was dropped as first-team doctor.

Carneiro and Mourinho clashed after she ran on to the pitch to treat Eden Hazard during their season opener against Swansea City, leaving Chelsea with nine men.

Following his criticism of the doctor, the Football Association cleared Mourinho of using sexist language towards her after he denied any wrongdoing.

She did not appear on the bench again before parting company with Chelsea.

Chelsea narrowly beat a midnight deadline last month in filing their defence – coincidentally the same day that Mourinho was sacked as manager.

Carneiro wants to be reinstated in her role as first-team doctor, as well as damages for sexual discrimination from Mourinho and a personal injury compensation and aggravated damages from Chelsea.

Mourinho could be told to pay Carneiro hundreds of thousands of pounds if she wins her case, and the club failed to indemnify Mourinho as part of his compensation package.

Chelsea declined to comment.
