I was 13/14 that season and stood at the back of the family centre in those days, me and a mate would stand on the slopping section of the back wall hanging on to the metal spikes so we could see over everyone. During the Norwich game I slipped and banged the back of my head on the steel beam, made an almighty crack. Stewards came running up and took me down to the first aid area at the entrance to the tunnel. They patched me up and let me leave to go back up to the family centre as the half time whistle went, I stood there as all the players went past me saying hi or something to Letiss who patted me on my head as he passed, it was at the time the greatest moment of my life.
That season was amazing and I was lucky enough to go to almost all the games home and away as my dad took me and a friend all over, only missed a few midweek away games.
As with the OP I think the Liverpool game was one of the best, also up there for sheer excitement and joy was the cup replay at Old Trafford a couple of years later when we knocked United out on penalties, Flowers ran the length of the pitch after saving giggs's penalty, I was going nuts hanging onto the fence at the front of the stands, made my debut appearance on tv as the saints players were celebrating right in front of me and my mate, I remember going to school the next afternoon really tired but I couldn’t wait to get there and gloat. (I went to school in Gosport so loads of Pompey & Man U fans)
