Celtic 3-3 Cluj
Griffiths makes an immediate impact, hassling the defence and winning a free-kick out of nothing on the left.
From the set-piece, Scott Brown heads through to the find the striker darting towards goal, but he hasn't got the space to catch and finish after nodding beyond Arlauskis.
Celtic 3-3 Cluj
We've been here before. Celtic need a goal. Neil Lennon gives Leigh Griffiths the nod. Off comes Olivier Ntcham. Can Griffiths be the hero again?
Cluj's hero, two-goal Billel Omrani, is being withdrawn for the more defensive Andrei Muresan.
Six minutes left. What does this mental game have in store for us next?

Quote MessageCeltic's defence went to sleep when you have to react positively.
Billel Omrani
Image source, BBC SportWow. Bedlam. Cluj hit Celtic with another grievous blow.
Scott Bain denies Alexandru Paun's shot, but he can't get the ball to safety. The Celtic defenders are nowhere to be seen, but Billel Omrani is right on hand to smash the ball into the net.
Once again, Celtic are heading out. Once again, they need another goal. This is a crazy night under the Parkhead floodlights, but it's threatening to end in darkness for the home side.

Quote MessageAn incredible night of European football at Celtic Park. But still a huge 15 minutes for Celtic. The intention for Cluj will be to get the ball into the wide areas and then get it in the box.
Ryan Christie
Image source, BBC SportThis is bonkers! A topsy-turvy belter of a European tie.
Odsonne Edouard is instrumental again, sneaking his way in behind the Cluj defence and cutting back for Ryan Christie to flick into the empty net. That's eight goals for the season for Christie.
Cluj's lead lasted just three minutes and there are still 13 to go. Another for the Romanians would still put them into the play-off...

Quote MessageScott Brown at the back post was struggling to get a header to the ball. I don't know if he intentionally handled it but it certainly struck his hand.
Billel Omrani
Image source, BBC SportBillel Omrani scores. His penalty is fired low to Scott Bain's right, the Celtic goalkeeper gets a hand on it, but can't keep it out. Big, big moment. Celtic, as things stand, are heading out. What a finale we have in store.
Celtic 2-1 Cluj
Cluj have a penalty! It looks like Scott Brown has been penalised for handball. What a chance for Cluj. Celtic Park is stunned.
Celtic 2-1 Cluj
Here come Celtic yet again, as Forrest cuts inside from the right angle of the box, and blasts a left-foot shot that Arlauskis beats away.
Celtic 2-1 Cluj
Celtic fans have been serenading Odsonne Edouard with their take on the famous Stone Roses number.
Here's a look at the Frenchman's razor-sharp finish, the goal that is currently sending Celtic into the Champions League play-off.

Celtic come zipping away on the counterattack with Edouard's knock-down bringing the midfield runner surging forward.
Ryan Christie gets hold of the ball and plays in Mikey Johnston, but his fizzed low ball across the face of goal is just beyond Edouard.
Celtic 2-1 Cluj
Celtic have looked so much slicker and more threatening in this second half. Their distribution has been snappier, and that's been key to breaking down a vigorously high-pressing Cluj.
They were handed a huge opportunity with that defensive mix-up, but Odsonne Edouard still had to be good enough to stick it away. Two very well-taken goals.

Quote MessageI don't know what the two Cluj defenders are doing, they've got in each other's road. And Odsonne Edouard is sharp as a tack. But, it doesn't change anything. Cluj still know if they get another goal they are in pole position.
Odsonne Edouard
Image source, BBC SportOdsonne Edouard pounces! A horror show at the back for Cluj as two defenders swipe at an Elhamed cross, allowing the ball to bobble through to the unmarked Frenchman.
He's absolutely lethal, his first-time shot on the half-turn fizzing low into the Cluj net.
Celtic have turned it around, they lead 3-2 on aggregate, but they can't stop there. A goal for Cluj now would still be enough to send the Romanians through.
Celtic 1-1 Cluj
Yet again, James Forrest comes up with the goods for Celtic.
He's now scored four goals and 10 assists in 17 European matches since the start of last season.

Quote MessageBrilliant play again. Great one-touch passing. Celtic and the crowd are really up for it at the moment. But they've got to use their heads and not their hearts and make sure they think about the game.
Celtic 1-1 Cluj
Celtic really have their tails up now. Some lovely one-touch passing between Johnston and Christie sets the latter free on the bye-line, left of centre.
His cut-back finds Odsonne Edouard at the near post, but the Frenchman's clipped effort only finds the side netting.
Much, much better from Neil Lennon's men.

Quote MessageThis game's far too open now for my liking - far, far too open. A brilliant chance for Cluj on the counter, Bain had to be really lively to keep Omrani's shot out.
Celtic 1-1 Cluj
The game has detonated into life after that Forrest goal.
Cluj power downfield and Bain is forced to block Omrani, before Mateo Susic scythes down Olivier Ntcham.
