City were badly run postwar with a lack of ambition.
Late 60's early 70's divisions and boardroom struggles took their toll culminating in the appointment of carpetbagger Swales as chairman. This started the rot that continued until he was forced out. Exemplified by first side-lining Joe Mercer and then a dispute with Francis Lee that took him to Derby and another champions medal under Clough.
Swales continued in this vein all his time at City. Mid 70's Tony Book resuscitated the dying patient but Swales showed little support and quickly reverted to type as the small time huckster surrounded by cronies. Swales interest was in using City as a paycheck, massaging his ego and as stepping stone to social climbing within the FA
Joe Mercer had brought wisdom and integrity. Malcolm Allison a vision and recipe for success. Neither were valued with players treated as pawns, all secondary to the interests and whims of those who ran City. It was a prewar mentality in a postwar age. Players and staff were expected to know their place. This took precedence over results on the field.
