I guess I should really provide even more context to these events.
There was only rarely any stoppage time of any length in those days. The game would not have gone to penalties but a replay, if the scores were level after extra-time.
And, crucially, the FA Cup was THE competition for everybody in an era where it was one of the few domestic games ever shown live on television. I can still remember the crackle of excitement when it was decreed I should sit and watch the 1980 game, with my family, including my grandparents.
I could sense the anticipation with all the build-up on both main channels and this was clearly a very big deal.
I'd really got into football properly, by that I mean more than playing myself but following it, that season, with the purchase of my first Panini sticker album. I became obsessed very quickly and knew all the squads (and still do).
West Ham United were underdogs, as a Second Division side (like Southampton were four years previously), so I sided with them, particularly when my dad told me how one of their strikers, Pancho, had been a favourite of ours at Old Trafford. Pleasingly, he got the assist for Trevor Brooking's winner, if only there was such a thing as an assist in 1980 (admitting to me last week it was a shot not a cross), and I would not have to wait too long for these sort of days to belong to Manchester United.
