Anyone still unaware of what match officials are up against in football need only watch the moments after the final whistle at the Amex Stadium.
Several Crystal Palace players, Yohan Cabaye, Bakary Sako, Wayne Hennessey, still went to referee Andre Marriner to protest about Brighton’s winning goal.
Despite the fact they would have known that, this time, the official could be certain his call was correct.
‘I’ll prove it to you,’ Marriner appeared to be saying, in defence of his judgment.
