Manchester United cult hero, Ryan Giggs, has reportedly scored a sensational own-goal with revelations he had an eight-year affair with his brother Rhodri's wife, Natasha.

And reports say the 37-year-old Old Trafford legend has fled the United Kingdom to avoid media glare after emerged that his brother has now split with his wife.

The Sun reports that Natasha told News of the World that she has had a long-term affair with the Manchester United superstar.

Manchester United's Ryan Giggs

There had been calls to have Giggs Knighted having won virtually everything with Manchester United since making his debut in 1990.

But recent revelations that he had an affair with Big Brother beauty Imogen Thomas lifted the veil on hitherto football’s "Mr Clean."

The star, who started his career as a winger and lately used as a playmaker in a central midfield role is the most decorated player in English football history having won 12 Premier League winner's medals, four FA Cup winner's medals, three League Cup winner's medals and two Champions League winner's trophies.

The Welshman has been played for Manchester United 876 times and scored 159 goals.

And with his glittering football career dented by the Imogen fling, another scandal touching on his brother’s wife Natasha will raise serious doubts on his Manchester United future even as manager Alex Ferguson was scouring the globe to find his replacement alongside another hero, Paul Scholes.

"It's horrendous. He has no morals," Giggs's paternal aunt Joanna Wilson told the Daily Mirror. "It was one thing having an (alleged) affair with Imogen, but this is said to be with his brother's wife, for God's sake."
