Eva Carneiro, the former Chelsea first-team doctor who left the club after a public falling out with manager Jose Mourinho, criticised the English FA yesterday for the way it handled its investigation into the matter.

“I wonder whether this might be the only formal investigation in this country where the evidence of the individuals involved in the incident was not considered relevant,” Carneiro said.

The FA had failed to interview her to establish if she was the victim of alleged sexist abuse by the Chelsea manager, she said.

The FA said this week it was not taking any action against Mourinho following the incident at the opening league game of the season against Swansea on August 8.

Mourinho’s behaviour has been criticised by the FA’s own chairman Greg Dyke who said on Thursday that Mourinho should have apologised, while Heather Rabbatts, an FA independent board member, was also highly critical of the way the FA conducted itself.

Carneiro said that the FA had “chosen to ignore” some of the evidence, adding that they also failed to act when she was the subject of sexist abuse from West Ham fans last season.

“I was surprised to learn that the FA was allegedly investigating the incident of August 8 via the press,” Carneiro said. “I was at no stage requested by the FA to make a statement. Choosing to ignore some of the evidence will influence the outcome of the findings.”

Mourinho accused Carneiro and Jon Fearn, the Chelsea physiotherapist, of being “impulsive and naive” and failing to “understand the game” when they entered the field to treat Eden Hazard late in a match against Swansea.

Chelsea were already down to 10 men following the sending-off of goalkeeper Thibaut Courtois and Mourinho lost his temper when the pair went to treat Hazard, meaning the team were reduced to nine men.
