AN expert in Portuguese swearing from Oxford University has been employed by Chelsea Football Club at the Eva Carneiro employment tribunal.

The hearing is over whether former manager Jose Mourinho, who has just signed a deal at Manchester United, used offensive Portuguese language towards the Chelsea doctor during a match last season.

Jose Mourinho is expected to give evidence at the hearing brought by the former first-team doctor Carneiro.

Dr Carneiro alleges she was sexually discriminated against by the club's former manager, who allegedly abused her as she went on to the pitch to treat Eden Hazard.
