Within weeks of their European success, Waddell moved to the general manager position and his coach Jock Wallace was appointed as manager. The reasons for the 51-year-old Waddell relinquishing the reins at Rangers were never fully explained, but the triumph in the Cup Winners' Cup came 16 months after the 1971 Ibrox disaster, when 66 people died leaving the east terrace at staircase 13; after helping the families of the victims and forging strong links with supporters' clubs, Waddell was determined to complete the resultant reconstruction of Ibrox Stadium.
