I've never thought about it before, but looking back now, I too was emotionally drained.
I was staying with some friends in Freiern Barnet and the tube journey back seemed to take ages. Of course, I was the only City supporter on the train, but even so, I didn't feel like talking to anyone.
My abiding memories of the game are our players continually slipping (what's new?), feeling stunned when Gillingham scored their first and shell shocked when their second went in.
I'd just bought my first season-ticket and was contemplating watching Oldham, Stockport et al at Maine Road.
When SuperKevinHorlock scored, the lad next to me - Harvey, I think he was called - didn't even bother celebrating; he said something like, "What's the point? We've lost". Then when Dicky hit the equaliser, all hell broke loose. It was absolutel bedlam.
And right from that moment, I felt we would go on to win the game. Pulis had taken off his goal threats and replaced them with defenders to try to keep us out. When Dickov broke free in extra time and bore down on the Gills' goal, you could feel the tension in the stand. Of course, he didn't score and if he had, it would have denied a player - Richard Edghill - who had never scored for City, to bag the winning penalty.
A brilliant day and as others have said, Paul Dickov's goal probably remains the most important in the club's history, but for personal reasons Agüeroooooooooo! means more to me.
