At a game at this level with so much at stake, deliberate cheating on this scale has to be eliminated. If it can't be done by replaying games, than bans have to applied retrospectively.
I wouldn't think it all over the top for Henry to be banned from the World Cup completely.
He's already played there before, so perhaps instead of asking the Irish to "deal with" not qualifying, we should be applying it to Henry.
Sorry mate, you got your team through, but frankly with your actions you don't deserve the opportunity to represent your country in the premium event.
.. deal with it.
His offence was punishable by a yellow card. A red at an absolute push. So how can you justify punishing that exact offence with a tournament ban?
That's like sentencing someone to death for stealing some biscuits.
