I think what Febbos is saying in post # 35 is that the score after 90 mins is the determining score in the cup match. If not, you've eliminated 1/3 of possible final results (a DRAW), which doesn't occur in non-cup games.Sorry, Canada. The 90 minute score is irrelevant. It's the score after added time that matters. Ask Fergie.
I may have misunderstood Febbos explanation however !
