Well, that's all from me on a strange old night for Celtic. The hosts were on the wrong end of a 3-1 defeat but still progress to the last 32.

Thanks for your company, Make sure you join us again for a busy Scottish Cup weekend.

John Guidetti will be eligible for the round of 32, having missed the group stage signing deadline. But is that enough? Do Celtic need to strengthen in January or is just a case of getting the best out of talents already at the club like James Forrest and Kris Commons?

Some of the teams already through as group winners and therefore possible opponents for Celtic: Fiorentina, Everton, Inter Milan, Dinamo Moscow...

"Everything is possible," answers Ronny Deila on Celtic's chances in the knock-out rounds. "If we can handle this team (Salzburg) that is the level we need to be at."

Problem is, they didn't really handle Salzburg at all, did they?

That's Celtic been beaten at home by Legia Warsaw, Maribor and now Salzburg this season.

Celtic manager Ronny Deila

"We are happy to be going through but we wanted to do it ourselves. We opened the game very poorly but showed courage to come back and I'm proud of the second half; we really put them under pressure. Salzburg has shown themselves a very good team and the best teams are going through."

Former Celtic midfielder Murdo MacLeod on BBC Radio Scotland

"Celtic fans won't be going home happy after a 3-1 home defeat but they'll be energised again when the knock-out round comes."

Stephen Gillespie on Twitter: "People are determined to take nothing but negatives from Celtic's qualification from their Europa League group with a game to spare..."

Andy Porridge on Twitter: "#bbcscotfootball 'I think we can reach the final or semi-final' -Denayer. Let's hope so. CFC got a free pass from Astra tonight."

Are Celtic getting any better asks Tom English on BBC Radio Scotland then answers his own question with a firm "no".

So Celtic will be playing Europa League football next year but it's all a bit anti-climatic after the chasing Ronny Deila's side were given in the first half hour.

The 12 group winners along with the four teams dropping out of the Champions League with the best records will be seeded in the round of 32.

Kenny Matthews on BBC Sport Scotland's Facebook, external page: "Paid the price for leaving the most creative player on bench until it was too late... Never mind we have qualified."

Celtic have one more match to play in Group D, with a dead-rubber visit to Croatia to take on Dinamo Zagreb on 11 December.

The Romanian Cup winners leapfrog the Croatians into third place in Group D but cannot catch Celtic.

BBC Scotland's Richard Wilson at Celtic Park

"Celtic's second-half revival fell short, although Salzburg's late third goal wasn't reflective of the balance of play. Celtic will need to improve to go further in the Europa League, but they have at least made the knockout stages despite losing to Salzburg. Much work still to do for the manager Ronny Deila."

Salzburg stretch their lead as a low shot from Sabitzer is saved by Craig Gordon's outstretched leg and the ball loops up for Keita to nod into an unguarded net.

We'll get three minutes of stoppage time.

No real cavalry charge from Celtic as the game looks like fizzling out. Salzburg are doing the pressing as the 90-minute mark approaches.

It's still 1-0 to Astra over in Romania, with Dinamo Zagreb needing a win to have any chance of catching Celtic. We're into the final five minutes at Celtic Park as the hosts seek to preserve their unbeaten record in the group.

Lovely interchange between Emilio Izaguirre and Stefan Johansen as the Celtic left-back runs on to a cute back-heel but the shot from a tight-ish angle is too high.

Celtic have been much improved in the second half. Can they find another goal for a second 2-2 draw against Salzburg in this campaign?

BBC Scotland's Richard Wilson at Celtic Park

"Celtic have been much more threatening and self-assured, and the substitutions have all been bold, with Forrest, Commons and Tonev all coming on. Salzburg are no longer in command, but carry a threat of their own. Much still to play for in the final quarter at Celtic Park."
