Absolutely 100 % serious. There was a draw in Italy 90 as well between Holland and Ireland to decide 2nd and 3rd place - 3rd place went through back then but it was necessary in order to determain who the teams were to meet in the 2nd round.
I don't think so. Actually I know so as there was a draw in 1990 between Holland and Ireland after the group stages. If it was like you said then a draw wasn't necessary ! Don't think Ireland and Holland had the same ranking.
Could you please document what you're saying?? I have read everywhere that it is as I wrote earlier!
