Eden Hazard is set to be called as one of Eva Carneiro’s star witnesses when her claim against Chelsea for constructive dismissal is heard next year.

The former team doctor left her role at Stamford Bridge after manager Jose Mourinho publicly criticised her for rushing onto the field to treat the Belgian winger during the club’s draw with Swansea City in August.

The Chelsea manager felt that Carneiro’s intervention, alongside club physiotherapist Jon Fearn, was “impulsive and naïve” as it left his side briefly down to nine men in the game’s final minutes, following the earlier dismissal of goalkeeper Thibaut Courtois.

However, after having a near-perfect first half in terms of his defensive work, he panicked while trying to clear Johnson’s cross out of Walters’ way, and it eventually fell to goalscorer Arnautovic. 2015 Getty Images Chelsea player ratings vs Stoke City John Terry - 4 out of 10 Should have communicated better with Baba Rahman in the build-up to the opener after running out of position to try and track the run of Johnson – but ultimately failed to do so after he allowed the Stoke defender to get his cross in. Chelsea player ratings vs Stoke City Baba Rahman - 4 out of 10 Lost the battle on the left flank with Shaqiri several times – getting a yellow card for a foul on the Stoke winger in the process – before failing to do enough to stop Johnson from getting his cross into the box in the build-up to the opener. Chelsea player ratings vs Stoke City Nemanja Matic - 5 out of 10 Kept Bojan quiet in the first half, winning tackles and distributing the ball well although he did deliver one disappointing pass to no one as Chelsea looked to attack one final time in the first half. However, he struggled to keep a hold of Stoke’s attacking players in the second period. 2015 Getty Images Chelsea player ratings vs Stoke City Ramires - 5 out of 10 Had two great chances to hand Chelsea the opener in the first half but poked his first wide before being denied by Butland with his second. Chelsea player ratings vs Stoke City Eden Hazard - 6 out of 10 His pace caused Johnson several problems and the Belgian was important in driving Chelsea’s attacking plays forwards as well as setting up his teammates for chances although they couldn’t convert them. Chelsea player ratings vs Stoke City Pedro - 6 out of 10 Linked up well with Willian and Hazard and ran riot across the width of pitch in the first half before being unlucky to hit the post as Chelsea trailed 1-0.

If called upon, Hazard would be asked to confirm whether he asked match referee Michael Olivier for medical attention before Carneiro and Fearn entered the field of play.

Television footage appeared to show the 24-year-old appealing for help but only Hazard is able to confirm that any conversation took place.

The Belgian, who won both the Professional Footballers Association’s and the Football Writers’ Association’s player of the year awards last season, is reportedly reluctant to involve himself in the case but could be compelled to give evidence at the tribunal stage.

Carneiro was relieved of her first team duties following the incident and subsequently did not report for work, claiming her position was untenable.

The Gibraltar-born medical specialist formally left the club last month. Having failed to agree a severance package with Chelsea, she is now bringing a claim for constructive dismissal against the club.

A hearing, conducted in public, will take place if no out-of-court settlement can be reached between the two parties.
