The Norwegian has praised two of Celtic's younger players.
And he feels the duo will have benefited from the experience of the Bhoys' European heartache.
The Norwegian is quoted as telling reporters: "I know the fans expect more and us players expect much more also.
"But this year we didn't manage it and we need to learn from it.
"We have a lot of young players doing really well like Kieran Tierney and Scott Allan came in and played well. So it is about experience."
Allan featured against Fenerbahce and could provide potential for the future. Tierney, however, has definitely shown plenty of promise.
Even during Celtic's lowest moments in the Europa League, the 18-year-old has stood out. Perhaps the teenager is yet to let disappointment break his spirit at such a young age but the likelihood is his talent will see him shine in the future.
Celtic's poor campaign will certainly provide a useful experience for their younger players such as Tierney and Allan - in that they won't want to experience such defeats again.
For the Bhoys' more senior players, though, (Johansen more than others, for instance), there can be little taken away from a poor season in Europe in the way of positivity.
