WIGAN Athletic manager Steve Bruce recently admitted he didn't know the offside rule or what kind of dangerous tackle constituted a sending off offence.

Then West Ham United boss Harry Redknapp said he didn't understand why his January signing Jermain Defoe wasn't allowed to play against his old club, Spurs.

Match of the Day pundit Alan Hansen quickly followed up by saying he also didn't understand the offside law and accused referees of not knowing them either.

Is it any wonder there's so much controversy in football when no-one knows the rules?
