Badges can be deceiving. Birmingham City have a football on theirs.
I remember going to their old ground in 1987, what I don’t remember is seeing the ball. It was that packed all I saw were people’s backs and shoes. I think I saw Warren Aspniall st one stage taking a throw in. I think it was 0-0. Probably I think that about sums up any rivalry with Stoke. Punched well above their weight for many years, also vaguely remember a few of them trying to bully a couple of us on a train back from Manchester.
