The 51-year-old has risked humiliating the Al Nasr technical director by speaking about her sex life.
While Dell'Olio did not mention Eriksson by name, she told ITV's This Morning: "I did [fake it]. I can't remember why. It didn't mean that I wasn't having pleasure. It was something I did to make my partner happy."
The couple began a relationship in 1998 before splitting up in 2007 following alleged affairs by the former Leicester City boss.
