Assistant Manager Sean Fallon was acting manager for most of the season as Manager Jock Stein suffered a serious car accident that required months of recovery.
Celtic reached the finals of the League Cup, where they lost to Rangers,[1] and lost in the third round of the Scottish Cup to Motherwell.
In the European Cup Winners' Cup, they reached the Quarter-finals, where they drew 1-1 on aggregate to East Germany cup champions Sachsenring Zwickau and lost 5-4 on penalties.
In earlier rounds, they had defeated Iceland's Valur and Portugal's Boavista.
