The Yaya FA Cup goal could have been a one-off, just a fleeting moment where City finally get a good result, like the 3-1 Maine Road Final Derby or the 4-1 at the new COMS. So that's not when it was for me.
Neither was it when we won 6-1 at the Swamp. That was a great performance which stunned the Rags who underestimated us, but that's not when things changed.
For me, it was the home derby of that same seasons, Kompany's 1-0. United now KNEW what they were up against. They KNEW they had to beat us. United sides in the past would have come out and dealt with the threat, but we were too composed, to determined, too soild. And we won. We did the job and now United were panicking. But for me, hearing the stadium rocking, singing 'Na Na Na City' having just done the double over the Rags, I knew things were changing.
