I was not there as i was only 5 at the time. Didn't go to my first City match until i was 10. I vaguely remember it being on tv in the front room. My overriding memory of it is car aerials having Sky Blue ribbons tied to them in celebration, well into the 90's!
It was a great final though. As Muddy Retriever rightly says, the semi was even better.
As a kid the cup really meant something. The league wasn't so important to me, i couldn't quite understand the importance of the bread-and-butter slog of an entire season. But perhaps because of the 87 legend, the FA Cup was everything.
My biggest FA Cup memory came a decade later when we had a really strong "entertainers" team... we had a sraightforward 3rd round tie, then hammered Derby at home in the 4th... looking at the 5th round draw, we just seemed to know we were going to get Villa or Manchester United, and inevitably we got Villa, away.
In my era that was the big game and rivalry... Leicester/Wolves/etc were league(s) below and Villa were a successful side, we'd never beaten them away in 104 years. We totally deserved the win and should have been 3 or 4 up before we eventually got in front. Officially the away crowd was 8000... we had the traditional away end, then half the side stand. But when we scored, nearly all the family stand went up, and significant sections of the Holte End, it was chaos, there must've been 15000 city there.
That game was/is my single greatest memory as a city fan.
In the next round we were home to Sheff Utd who were division below. We couldn't do it at home and it went to a replay at Brammall Lane, and we conceded in the final minute and it went to a pen shoot-out. Inevitably we lost. It was the only time i can recall being in tears over a football match.
Really thought our name was on the cup that year. We'd have had Newcastle in the semi, who were were simply superior to at the time. Arsenal would have been the final, and on a one-off match i'd even have backed us against them. In fact that season we played them on a live Sky match on Boxing Day, when we beat their great side 3-2 in one of the best matches i witnessed at Highfield Road.
Such a shame that the cup has become so irrelevant nowadays.
