That's all from us tonight. Thanks for your company and join us tomorrow for that Scottish Premiership game in Glasgow.
MBHAN: Scott Brown's influence on this Celtic team can't be underestimated offers so much bite, drive & leadership #bbcsportscot
Next up for us is tomorrow's Scottish Premiership game between Partick Thistle and St Mirren at Firhill.
Next up for Celtic are Dinamo Zagreb, who signalled their worth and intent by thrashing Romanians Astra 5-1 in the other group game in Croatia.
Celtic's midfield at times were left aimlessly chasing the ball like a bunch of schoolboys by their classy opponents tonight.
But, thanks to a brilliant goalkeeping display together with a home defence as fragile as their own, the Scottish champions will leave Austria with a point that should give them heart for the Group D campaign to come.
"Celtic will be frustrated not to have got a point, but they have no right to be frustrated as they would not have got that point if it had not been for the brilliance of Craig Gordon. Everybody is delighted for him to come back from injury the way he did - a great story - and to get him for nothing after selling Fraser Forster for £10m is the best bit of business they have done for some time."
"Celtic will be satisfied with a point against a team who are the top seeds, but Salzburg are not world beaters. They are a decent team but nothing more and that's the disappointing part of it."
"You would have taken a point away from home against the top seeds in the group - a team with a good reputation."
"I've never seen so many bad headers in one match - by both sides."
Stefan Johansen limps off and is replaced in the Celtic midfield by Beram Kayal.
Jonathan Soriano failed to break into a star-studded Barcelona side. However, the Spanish striker has an impressive strike rate with Salzburg and has now scored 78 times in 82 appearances.
Celtic are not sitting back and satisfied to take a point. Will the Scottish champions pay for their adventurous spirit in the closing minutes as this Salzburg side are well capable of a third goal given the visiting defence's fragility?
Mirren White: What has happened to the defence recently? Leaving holes all over the place and seem afraid to tackle. #Celtic #bbcsportscot
Craig Gordon has made Celtic fans forget the loss of Fraser Forster to Southampton in the summer with some superb performances. However, he might have been slightly slow going for Jonathan Soriano's equaliser, or I am expecting too much of man who has not long returned from two years out of the game through injury?
Former Barcelona striker Jonathan Soriano is given another chance to line-up a free-kick 22 yards from goal and this time makes Celtic pay as his curling effort beats Celtic goalkeeper Craig Gordon.
Anthony Stokes has a great chance to extend Celtic's lead, but Christian Schwegler makes an excellent block in front of goal to deny the substitute.
Joanathan Soriano's free-kick takes a deflection off the Celtic defensive wall and into the arms of goalkeeper Craig Gordon.
Alan again goes close to a second goal of the night for Salzburg, but the Brazilian striker's low drive from the edge of the penalty box goes a couple of fee wide.
Celtic scorer Wakaso Mubarak blots his copybook with a bit of play-acting after a tackle. He did go down heavily but looked up at the referee before beginning to roll about in pain after a delay of a few seconds.
Anthony Stokes comes into the Celtic attack in place of Stefan Scepovic, with the Serbian having been quiet tonight apart from that ambitious long-range lob into the side-netting.
Celtic midfielder Callum McGregor has been virtually anonymous so far but bursts into life and sends a cross into the box that is headed away by Jonas Ramalho.
And Scott Brown's volley from all of 25 yards is diverted off the Brazilian defender's shin, deceiving goalkeeper Peter Gulacsi in the process.
Craig Gordon is the Celtic hero again with a great double save.
The goalkeeper pushes away Marcel Sabitzer's low drive one-handed and, when the ball leaps into the air, Alan's header is goalbound until Gordon recovers to palm the ball off the line and wide.
Stefan Scepovic almost puts Celtic back in the lead out of the blue with an audacious lob from 40 yards.
The Serbian striker's effort beats goalkeeper Peter Gulacsi but nestles into the side netting.
Alan threatens to score his second of the night with a nice turn at the edge of the Celtic penalty area.
However, his curling effort is turned wide by goalkeeper Craig Gordon at full stretch.
The Scottish champions will be delighted that the former Scotland number one managed to overcome long-term injury to sign during the summer as Gordon has been their saviour tonight so far.
Salzburg are swiftly back on the attack and Andreas Ulmer has the first shot on target of the second half, but goalkeeper Craig Gordon makes a simple save at the near post.
Celtic kick off the second half, with no substitutes being made by either side at half-time.
"When it comes to Europe, Efe Ambrose is not just up to it. He started his Celtic career well, but he is a liability and teams know they can attack him down that right-hand side."
"Your heart's in your mouth whenever a team attacks Celtic and they have to think about that as a team like this will cause problems."
Andrew Priestly: The exotically named 'Alan' scores against Celtic. Who'll score next for Salzburg? 'Dave' or 'Jim'. #bbcsportscot
Jenni: Wakaso Mubarak, welcome! What a way to mark your debut.
In this evening's other Group D fixture, Dinamo Zagreb are leading 3-0 at half-time against visitors Astra Giurgiu with El Arbi Hillel Soudani scoring a hat-trick.
The waves of attack continue to lap onto the Celtic shoreline and striker Marcel Sabitzer's grass-cutter flashes wide of the far post from 22 yards.
Celtic captain Scott Brown is booked for a trip on Swiss defender Christian Schwegler. The aggressive Scotland midfielder has to be careful now considering his aggressive style.
A through ball from Christoph Leitgeb finds Alan stealing in behind the Celtic defence. The shot from the Brazilian striker - full name Alan Douglas Borges de Carvalho - takes a deflection off defender Efe Ambrose and spins over stranded goalkeeper Craig Gordon.
Celtic are having to weather some sustained pressure from the home side, who are dominating possession.
Celtic defender Virgil van Dijk is fortunate not to go into the referee's book with a foul on Jonathan Soriano.
The Spanish striker takes the free-kick himself and his floated ball to the back post finds Jonas Ramalho unmarked and the Brazilian defender's header is tipped just wide of the far post by the fingers of goalkeeper Craig Gordon.
A superb cross from Emilio Izaguirre finds Kris Commons in space at the far post, but the Celtic midfielder is unable to control his attempted volley to find Stefan Scepovic in front of goal.
Celtic threaten once more and Scotland midfielder Scott Brown fires wide of the far post, although a couple of team-mates lurking in front of goal complain that a pass might have been the better option.
Celtic full-back Efe Ambrose, who has not been in his best form so far this season, is booked for a shove on Marcel Sabitzer. Striker Jonathan Soriano's low free-kick is well smothered by goalkeeper Craig Gordon at the near post.
Celtic live dangerously as Salzburg look to reply immediately. Slovenia midfielder Kevin Kampl is given too much room at the edge of the penalty box and his curling drive is a foot wide of the far post.
Wakaso marks his Celtic debut with a superb finish to open the scoring.
Captain Scott Brown's header into the path of Kris Commons allows his fellow midfielder to play the ball low into the path of Wakaso and the Ghana winger strikes a low controlled drive curling into the far corner of the net from 18 yards.
Salzburg defender Andreas Ulmer is booked for a hand ball and Celtic win a corner following the free-kick.
The first corner of the evening goes to Salzburg and it leads to a fierce drive from Marcel Sabitzer that slips a couple of feet over the crossbar.
"Around 400 Celtic fans inside the Red Bull Arena for Salzburg v Celtic. Looks like a crowd of 15,000 and a warning for the visitors, Salzburg won all six of their group games in this competition last season."
Traffic is generally in the direction of the Celtic penalty area. However, the Scottish champions, marshalled by Virgil van Dijk, have not presented the home side with a glimpse of goal as yet.
