It was subsequently proven years later that Belgium's leading club Anderlect were bribing referees at the time. They beat Nottm Forest 3-0 when Forest were a top european side subsequently proved to be thanks to a bribed referee. I have no doubt Raul Nazare was bribed by the Belgians. I've seen plenty of bad refereeing in my time and even blatant biased referees but nothing even close to this one.
We were done v Bulgaria in 77 thanks to a perfectly good goal being disallowed at 1-1. However France were also done there too.
My worst experience away was definitely Cyprus 2006.
