Not sure which is the worst world cup out of this or the 2010 one, both were bad, this one quite defensive, i don't remember many high scoring matches, that the back pass rule was introduced a couple of years later.
Argentina fluking there way to the final, they only scored 5 goals in 7 matches[2 goals in the knockout rounds], the final itself was dreadful too.
Last world cup featuring the old USSR & Yugoslavia, before the break up of those countries.
Group F, consisting of England, Ireland, Netherlands & Egypt dubbed group of death played like it, only 1 win from 6 matches in the group & that was England vs Egypt, with Mark Wright scoring the winning goal
Germany vs Netherlands second round match, was quite feisty match, Frank Rijkaard & Rudi Voller both sent off midway through the first half, which lead Rijkaard to spitting at Voller, i can still see the phlegm on Voller's perm
I do remember summer 1990 being quite a glorious summer too, loads of sunshine in the UK
