Celtic have missed out on the lucrative group stage of the Champions League for the last three seasons.
And they face an uphill task to avoid a fourth campaign without being at the top table of European football.
New boss Ange Postecoglou admitted the club haven't been properly prepared for such a huge challenge so early in his tenure.
The former Australia boss hasn't had time to get the players in that he wants or his ideas across but they still managed a 1-1 draw in the first leg of their qualifier at home to FC Midtjylland.
With the away goals rule scrapped, it isn't beyond Celtic to progress but even then they would almost certainly meet PSV Eindhoven in the next round and that would be a step up again.
Despite the Danes struggling to mount a serious threat in the first leg, they did leave Glasgow with a lifeline thanks to a shocker from Vasilis Barkas which cancelled out Liel Abada's opener.
Bo Henriksen will be confident that his side can get the result needed to continue their European adventure but they hardly looked like great shakes in Glasgow.
