Spain/Nigeria was quite good too... And I remember Romania knocking Argentina out of USA '94. That was pretty classic aswell! Why don't you set up a poll to vote for the best game of all time?
In my living memory, which admittedly is not a long time... the Man U/Arsenal FA Cup semi-final in their treble winning season must come near the top. Also Charlton/Sunderland division 1 play-off final that went to penalties. Then of course there's Man U/Oldham semi-final 1994, and the Man U/Bayern champions league final. Most exciting game I've seen at layer road has to be the Paul Abrahams golden goal which put us into the Auto Windscreens final. Liverpool/Alaves literally had everything... TWO red cards, TWO disallowed golden goals, amazing saves, a penalty, a disputed penalty, an amazing come-back, NINE goals (and quiality ones at that), extra time, and finally an own-goal to settle it!
What's everyone else's best game in living memory?
