Another dramatic European night at Celtic Park saw the Hoops defeat Astana thanks to a last gasp Moussa Dembele penalty to progress in the Champions League.
Celtic have overcome their Astana test, but what did we learn about Brendan Rodgers' side during their Champions League victory?
1. Roberts can flourish at Celtic
The 19-year-old once again showed his quality on such a big occasion at Celtic Park on Wednesday night. The midfielder certainly gives the Hoops a different dimension going forward with his speed and directness when running at defenders.
He's shown during his spell at Celtic he is able to dictate games with his ability and with more and more games under his belt as well as the guidance of Brendan Rodgers he has the potential to go on further.
The on-loan Manchester City talent went off with a suspected hamstring injury, no doubt if Rodgers has any hope of reaching the group stages he will need his bright young star to light up Celtic once more.

2. Celtic must be more clinical
It was a spirited performance on Wednesday, although if Celtic are to progress further in the compeititon they will need to be more ruthless when the opportunities are given to them.
They were presented with a number of chances before Astana equalised and you started to wonder if it would be a night of missed opportunities.
If Rodgers has hopes of guiding the club into the group stages he will have to make sure his forward players can make the most of what they get, especially with much stern opposition awaiting in the play-off round. Tonight they had a number of chances, in the next phase they may only get one or two and it's important they make the most of them.
3. Hoops still finding their feet under Rodgers
It's evident to all that the Celtic supporters will have to wait some time to see the playing style of manager Brendan Rodgers come to fruition.
We saw in patches throughout the game that patterns of play are starting to come together, however the inconsistency is alarming which is certainly understandable considering the former Liverpool manager has only been in the job for six weeks.
We saw during his time at Liverpool a fast, high tempo, high pressing game which saw success, but Rodgers will certainly need more time to implement his style to his Celtic players.
4. Dembele may be on the rise
Much was made of the striker's move to Celtic from Fulham after scoring 17 goals for Fulham last term in the Championship, but his Celtic career so far stood at eight appearances and no goals.
It takes a lot for any player to step up for a penalty in the dying minutes of a crucial game, let alone a Champions League qualifier!
So for 20 year-old Moussa Dembele to calmly slot home the penalty could be what's needed to kick start his career at Celtic Park.
We've seen in the past a goal can change confidence as a striker, I'm sure Celtic fans will be hoping for a similar outcome this time round.

5. Rodgers may not have European nous
It's one thing managing in the Europa League but to step up to Europe's elite club competition will test Rodgers, he was outclassed during his short period in the Champions League as Liverpool manager where he was unable to guide the club past the group stages.
In periods against Astana a lack of tactical know-how in European football showed with Celtic being too open in periods where you may expect to play a slightly more reserved style while under pressure.
If Rodgers is to be successful in Europe with any club he will have to be more open to adapting against opposition to get a positive result especially against top teams in the play-offs.
