I just thought it was kind of relevant to point out - in my reckoning - if we beat the Dutch then it would be our biggest - and FIRST ever - knockout win against a big contender nation on foreign soil.
It looks like it would be the biggest. Lots of teams are contenders though. Denmark won in 92, Greece won in 2004, but if we'd knocked either of those out you'd argue they weren't contenders.
I realise now it was foolish of me to have embarked on this thread without providing FIFA World Rankings at the date of each match, as the matter is entirely subjective.
You're the one who brought rankings into it when you said Belgium in 1990 doesn't count.
