There've been a few bad moments, but the worst I remember feeling was the FA Cup game against the rags in 95/96. It was my first visit to the swamp, and we were robbed. That lot kicked us off the park, and equalised through a decidedly dodgy penalty (a sign of things to come, I guess as City were on the receiving end of a penalty decision from a corner that could be given every single match, but has never been given since). I remember it taking me more than a week to get over it, I was so angry, but it was a game that was symptomatic of how the two teams were treated.
And in my mind, looking back, it was the moment it all started to unravel for City...
