Celtic face an uphill battle to reach the Champions League group stage after suffering a 2-0 defeat to Shakhter Karagandy in Kazakhstan.
Neil Lennon's side had plenty of possession, but were ultimately undone by a lack of quality and killer instinct in the final third of an artificial pitch in the Kazakhstan capital of Astana.
They were also let down by their lack of ability to deal with crosses and high balls as Andrei Finonchenko netted from close range after a long throw-in had been flicked on with Emilio Izaguirre left ball watching early on.
Sergey Khizhnichenko added the second 13 minutes from time as he headed into the net from close range with visiting debutant Virgil van Dijk - who had a poor match alongside Steven Mouyokolo in central defence - left marking fresh air as the home man headed beyond the visiting goalkeeper Fraser Forster.
Celtic have time to turn this match around when they host Shakhter at Celtic Park a week on Wednesday, but they will need to produce much better from open play against a limited but towering home side.
PRE-MATCH: Virgil van Dijk made his first start for Celtic after joining from Groningen alongside Steven Mouyokolo in central defence. Nigerian defender Efe Ambrose was on the bench. Scotland winger James Forrest returned to the starting line-up after being on the bench at Aberdeen, but there was no place in the squad for new Dutch signing Derk Boerrigter, who had been toiling with an ankle problem.
12' GOAL! Andrei Finonchenko arrived to score from close range. Awful defending by the Celtic defence it must be said. Just a long throw and flick-on for the home man to net. Goodness know what was happening there.
18' SO UNFORTUNATE! Kris Commons sees a shot come back off the bar from distance. Not sure if that was over the line. What an effort from Commons from 30 yards out. Celtic should be level at 1-1.
28' ANOTHER CELTIC CHANCE MISSED! Georgios Samaras nods a couple of yards wide from Mulgrew's free-kick. Another golden chance for Celtic not taken.
52' MORE OF THE SAME! This time Emilio Izaguirre leans back and lifts a shot over the bar from 12 yards. What a chance that was, but not taken.
77' GOAL! Sergey Khizhnichenko rises to nods into the goal from five yards out. Awful defending again by Celtic. Truly awful as Van Dijk is caught on his heels.
TALKING POINT: Can Celtic turn it around? Of course they can. There are plenty of goals in this tie for them, but they need to be far more ruthless in front of goal at Celtic Park. They also need to be far more alert in central defence in dealing with long throw-ins and high balls. Was a poor display by them even if the plastic pitch did them few favours.
Shakhter are on the brink of becoming the first Kazakh club to reach the group stage after goals from Andrei Finonchenko and Sergei Khizhnichenko.
Celtic had 66 per cent possession and 17 attempts at target compared to only 14 by the home side, but could not convert their chances into goals.
Shakhter: Mokin 7, Vasiljević6, Poryvaev 6, Džidi 6, Maliy 6, Simevic 6, Vicius 6, Ghazaryan 6, Cañas 7, Finonchenko 7, Khizhnichenko 7..subs: Zenkovich 7

MAN OF THE MATCH:
Sergey Khizhnichenko (Shakhter): Sweated buckets for the cause. Caused the Celtic defence no end of problems. Scored the second, and never gave the visiting side a moment's rest all night.
