Scenario : A player scores a goal a yard away from the goal from an awkward bounce using his belly. Some opposition players shout hand ball (which they always do whether it is a hand ball or not). The referee does not see the hand ball and thinks its come off the abdomen/belly as the hands were down and tied across his own body, so the referee allows the goal. 30 seconds later the goalscorer then says to the referee that his "the ball touched his lower arm but his hands were down and tied so its not hand ball" Hence, referee now realises his mistake as the goalscorer bas admitted that it touched his hand. Hence, by law the goal should NOT stand. What should the referee do at this stage after he hears what the goalscorer has said to him? Is the statement from the goalscorer enough to overturn referees own decision or should he stick with his decision to avoid chaos?
