Many others have mentioned Barnes and Owen. But what needs to be added, I think, is this. They were the new guard when they first emerged. They came in very much as the youngsters (along with Ged Keegan), surrounded by a number of considerably older heads — Channon, Kidd, Tueart, Watson, Corrigan, etc.The veterans. They learnt at that school. Keegan was perhaps never quite good enough to make it, but Barnes and Owen should have spearheaded the transition to the early eighties, as ‘elder statesmen’ in their turn, to a different City team. Instead of a transition, what Allison did was instigate a rupture, pure and simple. Then, having done the damage, he fucked off (or rather, was fucked off by Swales). Football teams don't work like that. There has to be transition. It really is tragic. City had built enough over the late sixties and right through the seventies to be a powerhouse in the following decade.
Of course, Swales did as much damage as Allison himself. Much more, in fact.
