The problem is Arks it is a get out for refs who bottle it because of crowd pressure. They can make a report saying that they did not see an incident. Yes players should be punished retrospectively, but what about a penalty not given? The club cannot get a game replayed or the points back for a result that was manifestly adulterated. Replays and technology have got to be introduced, Rugby, Tennis, Cricket, even Horse Racing has a review facility and so should Football.
