I can confirm that, Neil Swarbrick was the 4th referee and I got to know him through work at BAE Salmesbury, he told me Dean would have given the penalty anyway if Sergio had missed, like you I don't know think my heart would have stood up to the pressure of Super Mario taking the penalty.I've posted this before in another thread, I did a job at Mike deans house few years ago, I asked him if Sergio went down would he have given the penalty, yes, 100% penalty he replied, i sit right behind the goal in the family stand, no way could I have watched mario taking the penalty, I'd have a heart attack
