• Carneiro will now not be involved in matches and training sessions • José Mourinho criticised doctor during draw against Swansea

Eva Carneiro, the Chelsea doctor, has had her responsibilities at the club scaled back after being on the receiving end of a rant from José Mourinho on Saturday, and she is not expected to continue being on the bench during games.

Carneiro will remain as the first-team doctor, working with the squad on a daily basis, but, as things stand, she will no longer attend training sessions, matches or enter the team hotel. Mourinho lost his cool towards the very end of his team’s 2-2 draw with Swansea City at Stamford Bridge, when Eden Hazard went down in the third minute of stoppage time and Carneiro – together with the physiotherapist, Jon Fearn – ran on to treat the winger.

The Chelsea goalkeeper, Thibaut Courtois, had earlier been sent off and, with Hazard briefly out of commission, Mourinho was worried about being vulnerable, with only eight outfield players, to a Swansea break for a potential winning goal. Mourinho gestured furiously on the touchline and he appeared to direct most of his anger towards Fearn. The flashpoint did not appear to have any great bearing on the result but Mourinho, who is obsessed by the finest of details, did not see it that way. He gave vent to his feelings afterwards, when he suggested that his medical staff did not understand the game.

“I wasn’t happy with them because even if you are a medical doctor or secretary on the bench, you have to understand the game,” Mourinho said. “If you go 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 outfield players in a counterattack after a set piece and we were worried we didn’t have enough players left.”

It sounded, at the time, as though Mourinho was using a tactic to divert attention away from a disappointing result, but his frustration at the club’s doctors has been building, despite the squad’s injury record being generally excellent last season.

Mourinho said on several occasions over the summer the medical staff had to improve, a sentiment that was motivated, perhaps, by his annoyance at the hamstring problems that have affected Diego Costa.

The striker finished last season with the injury and he has continued to feel it over the summer. The importance of a fully fit Costa to Chelsea’s Premier League title defence is lost on nobody.

Carneiro made a rare Facebook post in response to Mourinho’s outburst and there is little doubt she has the sympathy of the public on her side. “I would like to thank the general public for their overwhelming support. Really very much appreciated,” Carneiro wrote.

Mourinho was unhappy at Courtois’ red card, which the referee, Michael Oliver, gave on 52 minutes when the goalkeeper took down Bafétimbi Gomis. Oliver ruled Courtois had denied Gomis a goalscoring opportunity and he also awarded a penalty, from which the Swansea striker equalised. Chelsea appealed to the Football Association against the decision and Courtois’ automatic one-match ban, mindful that he would have to serve it at Manchester City on Sunday. The governing body, however, having heard the case on Tuesday, rejected the appeal.

With Courtois banned, Mourinho will turn to Asmir Begovic at the Etihad Stadium – the goalkeeper that he signed from Stoke City over the summer to cover the departure of Petr Cech to Arsenal. Begovic came on against Swansea after Courtois’ dismissal.

“For a club to be successful with a claim of wrongful dismissal, it must prove to an Independent Regulatory Commission via written and/or video evidence that the match referee made an obvious error,” the FA said, in a statement.
