Mourinho is said to ban Chelsea first team doctor Carneiro from training sessions, hotels and games after their touchline row

Dr. Eva Carneiro is arguably one of the most recognisable faces on Premier League benches, the woman doctor who Chelsea have relied upon to treat their injured players.

But in the space of only four days, Eva Carneiro's relationship with Jose Mourinho has deteriorated so badly that we may not see her again.

On Saturday, Carneiro and her colleague Jon Fearn angered the Chelsea manager by rushing on to the pitch to tend to Eden Hazard near the end of the 2-2 draw with Swansea.

Carneiro will remain as first-team doctor but will no longer attend first team matches for the club

Chelsea were already down to 10 men and Hazard receiving treatment meant that last season's Player of the Year had to spend a few moments on the touchline, leaving the champions vulnerable. Mourinho was furious.

'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,' said Mourinho.

'You have to know that when you have one player less and, in the end, you go on 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 players in a counter-attack after a set piece and we were worried we didn't have enough players left.'

Carneiro was hurt by that and Chelsea fans rushed to send her messages of support. On Monday she posted on Facebook: 'I would like to thank the general public for their overwhelming support. Really very much appreciated.'

But instead of patching things up with her, Mourinho took more drastic action. The 41-year-old, who was born in Gibraltar, will keep her job title as first-team doctor but she will not be allowed at training sessions, matches or the team hotel.

That surely puts her future at the club in doubt. Fearn is likely to receive the same treatment but a late decision will be made on him as the club need a physio on the bench for Sunday's crucial match at Manchester City.

Carneiro was promoted to her role with the Chelsea first team by Andre Villas-Boas in 2011 and has since worked with Roberto di Matteo, Rafa Benitez and now Mourinho.

Born to a Spanish father and British mother, she has studied at Nottingham University and Queen Mary University of London.

Carneiro spent time with West Ham before being appointed to the UK Sports and Medicine Specialist training program with the Olympic Medical Institute preparing athletes for the 2008 Olympic Games.

She spent some time working for the England women’s football team before joining Chelsea in 2009.

Sportsmail understands Mourinho’s decision has raised a few eyebrows at the club.

Players were said to be ‘completely shocked’ at the news of the doctor’s demotion, although they knew something was wrong as Mourinho had not been his usual jovial self, even with his favourite players.

It is also believed that not all members of the club’s hierarchy share Mourinho’s opinion that Carneiro was in the wrong.

... I think Mourinho has over-flogged this issue if you ask me
