For me it was the Man Utd vs Crystal Palace 1-0 win in 1990
I was 12 and been to France on school trip. The day we were coming back was on the Saturday for Cup Final. Made driver put Radio 5 Live on and listened to one of the greatest finals of all time unfold.
Glad in a way it finished 3-3 as got to see the replay on the Wednesday in which the shock call-up of Les Sealey proved to be one of many Fergie's inspired signings and Lee Martin went on to seal a great win.
Remember next morning I bought every newspaper i could see for the cuttings!!!
