Sven-Goran Eriksson misled the Football Association during the Faria Alam scandal, an Employment Tribunal ruled.
When questioned by FA executive director David Davies the England coach initially denied having an affair with former FA secretary Alam.
In 2004 Alam, then Davies' secretary, had affairs with Eriksson and then chief executive Mark Palios and left the FA soon after her affair with Eriksson was exposed.
The tribunal concluded that the FA did not sacrifice her 'to protect Palios' reputation'. Palios eventually resigned along with Colin Gibson, the FA's director of communications.
Alam made a string of allegations against the FA when she left Soho Square but the tribunal branded her claim of sexual harassment against Davies as 'a figment of her fertile imagination'.
Alam lost her case against the FA for sexual harassment, unfair dismissal and breach of contract last September but the Daily Telegraph report today that it is only now that the reasoning behind the tribunal's verdict has been revealed.
One section of the report, paragraph 7.22, concerns comments made by Eriksson.
'During the course of the interview, Mr Eriksson said to Mr Norbury (the FA-appointed QC initially investigating the Eriksson-Alam affair) that he had not been specific about his answer to David Davies, but that he had used the word `nonsense' when the allegation was put to him by Mr Davies and that he told Mr Davies that `his private life was his private life'.
'We are satisfied that the comment from Mr Eriksson supports Mr Davies' account that, when he first raised with Mr Eriksson the allegation about an affair, his firm view at the end of the conversation was that Mr Eriksson was denying the affair.
'Of course Ms Alam also denied it to him, and it was with that background that the Football Association, through Mr Davies and Mr Gibson, issued the statement denying the affair, the circumstances of which were the subject of Mr Norbury's enquiry.'
