The negatives from Celtic's 4-3 defeat to Dinamo Zagreb were clear for all to see.
The Bhoys looked all at sea in defence and the result left them only two points clear of the third-placed Croatians in their Europa League group.
But there is one major positive Ronny Deila and co can take from Zagreb that, combined with another factor, could potentially give Celtic all the hope they need in Europe.
Indeed, the fact that the Bhoys scored three goals away from home in the Europa League without their star striker means they could be well placed for the competition's knockout stages.
For John Guidetti was ineligible for the SPL champions' group-stage campaign. Now, though, the Swede is free to feature in Celtic's Europa League journey from February and beyond.
A three-goal haul in Zagreb would have likely turned into an even bigger one with Guidetti, meaning Celtic can chase any amount of away goals they may need in the second leg of the last 32.
Deila will, of course, have to sort out his worrying defence - which was nothing short of woeful yesterday - but, regardless of the opposition, three goals away from home is some achievement. Add Guidetti to the mix and Celtic could advance deep into the competition if they keep that kind of goalscoring form up in the knockout rounds.
