Massimo Bruno is allowed to weave his way infield and his shot loops up into the Celtic penalty box where Alan is waiting to rifle the ball past an exposed Craig Gordon from seven yards.
Salzburg are making all of the early running as Emilio Izaguirre clips the heels of Kevin Kampl on the edge of the penalty area. Again the free kick is scrambled clear.
Salzburg win a free kick as Virgil van Dijk bundles over Brazilian striker Alan. Soriano curls in a nice delivery which eludes Craig Gordon but is nodded away.
Celtic get the game started. Hold on to your bunnets.
Both teams go into pre-match huddles. Not long to go now...
Van Coupon on Twitter: "Craig Gordon will be busy. Team selection is awful. #bbcscotfootball."
BBC Scotland's Richard Wilson at Celtic Park
"A win over Salzburg would secure Celtic's passage to the Europa League knockout stages, and the responsibility in attack lies with Leigh Griffiths, a peripheral player under Ronny Deila. The defence will also need to be way to Jonathan Soriano, who has scored 28 times this season for Salzburg. Celtic Park isn't full, but there is anticipation in the air."
Salzburg manager Adi Hutter
"We have come here to win the game which would be important for the club and for me personally as it's my first season in the Europa League.
"I will enjoy the atmosphere but I can only be happy if we play well and my team wins."
BBC Scotland's Tom English points out that eight of the Salzburg line-up were playing when they demolished Ajax 6-1 over two legs in this competition last season.
Celtic manager Ronny Deila
"We have met good opponents in Europe but Salzburg have had some good results and been at a high level for a couple of years.
"They work hard together, they run a lot and it is hard to get your own passing game going.
"It is clear to us what we are going to meet so we just have to be up for it."

Celtic will need to keep a very close eye on Salzburg's red hot striker Jonathan Soriano. The Spaniard has banged in an incredible 52 club goals so far this year.
The 29-year-old began his career with Espanyol, moving across the city to join Barcelona in 2009, where he was a regular in the B team for three years but unable to dislodge the stellar cast of Lionel Messi, Zlatan Ibrahimovic, Pedro, David Villa and Alexis Sanchez at the Nou Camp.
Not all portents point in favour of Celtic though...
Adi Hutter's side are unbeaten in their last eight Europa League matches away from home. Salzburg are also the highest scoring team in the group phase with 13 goals from their previous four matches.
Captain Scott Brown reckons tonight's opponents are the best team Celtic have played all season - and the fittest. But the omens are good since no Austrian side has left Scotland with a victory in competitive European action after 13 attempts.
BBC Radio Scotland are providing live commentary from Celtic Park but we do not have online rights, so you'll need to dig out the old transistor and go listen in the car.
The sides drew 2-2 in their Group D opener in September, with Craig Gordon playing an absolute blinder for Ronny Deila's side. The goalkeeper has been in exceptional form since he joined the Scottish champions in the summer, reserving some of his best performances for this competition.
The Austrian and Scottish league leaders are vying to finish top of the section - both are unbeaten so far, with Salzburg - already qualified for the last 32 - currently two points ahead.
With free-scoring John Guidetti ineligible, there is a rare start for Celtic striker Leigh Griffiths and Callum McGregor gets a run in midfield as James Forrest and Kris Commons drop to the bench.
Celtic: Gordon, Matthews, Ambrose, van Dijk, Izaguirre, Mulgrew, Brown, McGregor, Johansen, Stokes, Griffiths. Subs: Zaluska, Biton, Scepovic, Commons, Tonev, Kayal, Forrest.
SV Red Bull Salzburg: Gulacsi, Ankersen, Ramalho Silva, Hinteregger, Schmitz, Kampl, Bruno, Ilsanker, Leitgeb, Alan, Soriano. Subs: Walke, Schwegler, Sabitzer, Keita, Laimer, Caleta-Car.
Referee: Halis Ozkahya (Turkey)
There are lots of permutations for tonight's match but let's keep it simple. A win for Celtic will guarantee progress to the knock-out phase, as will a draw or even a defeat if Dinamo Zagreb fail to win at Astra.
Good evening and welcome to our coverage of Celtic's penultimate Europa League group game, with Salzburg the visitors to the East End of Glasgow.
