I found that 'Good Luck' flag a bit Small Heath myself.
I thought it more a play on the fact that geographical location of most of their rival fan base was let us say not all that local to them.
A Blues equivalent would have been profanity laden and focused on Villa too.
Yeah and it's the same bollocks they would peddle, 90% of the genuine mancs I've known were reds.
Exact opposite in my experience. Man City drew their support overwhelmingly from the City. Utd were always boosted by outside support. He’ll, there were,and maybe still are, 30,000 registered Brummie Reds. Shame on them. Old Trafford isn’t even within the City’s boundaries, it’s in Salford.
It’s in Stratford in the Borough of Trafford which is what the flag was aimed at. They all shook my hand on the train int he way back to Manchester where I was studying.
As for support city used to have all of South Manchester but North Manchester, Salford, Trafford and Cheshire supported Manchester United historically
