Jose Mourinho to be investigated over claims of sexism

London: Chelsea manager Jose Mourinho could face a five-match ban after a member of the public complained he had used sexist and abusive language against former team doctor Eva Carneiro, Britain`s press reported Friday.

The Football Association said in a statement that it had "received an enquiry relating to an alleged incident during the Premier League fixture between Swansea v Chelsea on 8 August" but that it would make no further comment.

Mourinho criticised Carneiro when she ran on the pitch to treat Belgian star Eden Hazard at the request of referee Michael Oliver during the final stages of the drawn match.

Footage of the incident broadcast by Sky Sports showed Mourinho shouting angrily while watching Carneiro from the touchline, before exchanging words as she came down the touchline to return to the dug-out.

Mourinho demoted the Gibraltar-born medic straight after the game, and she has yet to return to the club`s training ground.

Under FA rules, players and coaches can be punished for using "offensive, insulting or abusive language and/or gestures". 

An aggravated breach, for instance a reference to gender, carries a minimum touchline ban of five-matches.

The FA is compelled to investigate the claim, which was made in the past few days, according to reports.
