The 24-year-old, currently on loan to Championship side Reading, had been accused of attacking the girl at his flat in Beckenham, south-east London, in September 2004.

Stack was cleared of one count of rape and another of sexual assault.

His friend, Allan Smillie, 24, was cleared of two counts of sexual assault.

The woman, from north London, went back to Stack's flat after meeting the player and his friend at a nightclub.

She claimed he had forced himself on her after she lay down in one of the bedrooms because she had been sick.

But the Republic of Ireland Under-21 international, who was on loan to Millwall at the time, maintained she had consented to sex with him.
