Portsmouth coach Avram Grant was the Premier League manager seen visiting a "Thai" vice den, Sun Sport reports.
Speculation had raged worldwide after The Sun revealed a top-flight boss spent more than an hour in the seedy massage parlour.
Creeping privacy laws in the UK - based on the Human Rights Act ?" meant the tabloid was barred from naming him last December.
But in the wake of England captain John Terry's failed bid to gag the press over his affair, Grant has been named as the manager visited the brothel in Hampshire.
Hampshire Police are investigating the parlour, which is staffed by Asian "massage" girls in Horton Heath, Southampton.
Israeli Grant, 54, has been wed for 16 years to actress Tzofit, 45. They have two children but she did not follow him to England when he moved here.
He faces being quizzed by vice squad officers over his visit to the brothel.
