All people are capable of life-long loyalty but City are one of very few clubs in England where this has been truly tested on a mass scale over decades. I'll never forget the first game of 1998-1999 season when 32,000 turned up to watch manchester City v Blackpool in the old Division 3 about 25 years after we had last won a trophy. We would have to wait another decade before won a league title and yet through that 35 years City fans stayed intensely loyal. Individual football supporters sometimes stick with their football club for life, but many don't. They stop going, and only come back if the good times return. City fans didn't do that. The worse it got, the more determined we became to stick it out.
God Bless Kun Aguero and all those blues who stood loyal and never quite made it to see that day.
