Brendan Rodgers left big-money signings Arne Engels and Adam Idah on the bench in Almaty
Now that Celtic's doomsday scenario has come true - ignominy in Almaty - there should be a reappraisal of the club's most egregious and self-inflicted exits in Champions League qualifiers in the last dozen seasons or so.
Maribor, Malmo and AEK Athens. CFR Cluj, Ferencvaros and FC Midtjylland. All wounding, all the cause of introspection and fury.
Some of those clubs had a big claim on being the greatest European bogey that caused the most damage to Celtic and the delusions of grandeur they have of themselves as a great European club.
The immortals of 1967 and the atmosphere on Champions League nights continue to do some seriously heavy lifting on that front.
