It wouldn’t really be the Celtic way to qualify without some drama.
A 5-0 first leg lead should have made the second leg a formality, even at half time with the score at 1-1 qualification looked routine with the bonus of an away win to enjoy.
Five crazy minutes at the start of the second half turned all those predictions upside down, with 20 minutes left to play the unthinkable was passing through the thoughts of more than a few fans.
Fortunately Olivier Ntcham killed off the nightmare scenario but the 8-4 aggregate threw up as many questions as answers.
As supporters debate various issues one man has got a greater grasp than any other- that man is Brendan Rodgers.
The review of the match will be underway before the charter flight gets off the ground in Kazakhstan with some big decisions needing to be made.
In defence the Celtic boss will need to decide if there is adequate cover for Jozo Simunovic, if the former Dinamo Zagreb man is missing does he have confidence in the defenders currently at the club.
With a week left in the transfer window it’s likely that more than Patrick Roberts will be joining up, with more quality additions Rodgers hopes of European football after Christmas can be realised.
