I thought the rule was, if you were going to attempt this type of corner, was that it had to be on the linesman's side, and you had to tell him? It happened once in a game with Man United and Chelsea, Rooney touched it, Giggs (I think) ran over and took it, Ronaldo knocked in the header, but it was disallowed because Rooney didn't tell the linesman.
All in all it was an appalling decision
