Brendan Rodgers makes another attacking change, with winger Scott Sinclair coming on, and defender Mikael Lustig making way.
Celtic 1-1 AEK Athens
Nervous moment at Celtic Park.
Kristoffer Ajer, who has already been booked, brings down Marko Livaja on the edge of the box. But Livaja's free-kick hits the wall, and Craig Gordon gathers the loose ball.

Great run from James Forrest to the right byline, and his cross finds Leigh Griffiths at the near post, but the substitute can't keep his header down.

Quote MessageIt's important Celtic keep that build-up but keep going wide as well. AEK are going to make it really congested in the middle of the pitch. James Forrest needs to keep his width on one side, Kieran Tierney on the other, and now they've got two strikers on the pitch to hopefully get on the end of something. Keep it moving quickly from side to side and try and get those gaps to appear.

Athens now settling in to defend what they have. Celtic probing in a bid to find an opening but 10-man AEK are working hard. They know this is a great result, as it stands.

Quote MessageCeltic can afford to go two up top now with the numerical advantage. With 10 versus 11 they don't need to worry about having that extra man in the middle of the pitch.
Celtic 1-1 AEK Athens
Konstantinos Galanopoulos earns two yellow cards in just seven second-half minutes.
"He's a young, 20-year-old player. His brain wasn't switched on," says former Celtic goalkeeper Pat Bonner. "It's advantage Celtic, now let's see if they can do something here."
Former Celtic striker Scott McDonald is incredulous: "How stupid is Galanopoulos? How silly a challenge that was. It's a definite yellow."

Brendan Rodgers sends on Leigh Griffiths to join Odsonne Edouard up front for the final half-hour.
The Scotland striker gets a huge roar from the Celtic faithful. Can he find a winner?

Celtic immediately on the attack again, as James Forrest tees up Callum McGregor, but his shot on the angle is blocked.
Second yellow card for Konstantinos Galanapoulos, who was only booked a few minutes previously, for a cynical foul on James Forrest. And that's his evening done.
Can Celtic capitalise on their man advantage?
Celtic 1-1 AEK Athens
Lovely bit of skill from Kieran Tierney, who is having a cracking game tonight. The ball falls to Olivier Ntcham, who unleashes a shot from 30 yards that is deflected wide.
Celtic 1-1 AEK Athens
Konstantinos Galanopoulos also goes into the book after a late tackle on Tom Rogic, who evaded the Greek player with a lovely piece of skill.

Quote MessageIt was a huge shot in the foot for Celtic. Psychologically it is a big test for them now. How do they respond to that? Brendan Rodgers will be saying 'Same again, get on the front foot like you did in the first half, but be wary of the counter'. They had one lapse in concentration, and that is what happens at this level in Europe.

Quote MessageIt is total frustration for Celtic. Up to 40 minutes it was such a good performance in Europe, from an attacking and defensive point of view, even without creating lots of chances. The way they went about their game was superb. But that last five minutes...We are left dwelling on the negative when there is so much positive about that first half.

It’s the away goal Celtic dreaded. The warning signs were there and it looked all too easy. Celtic must get back on top and find the tempo in the second half that saw them dominate most of the first. Fans that looked satisfied now appear a little nervous.

Quote MessageIt was poor defending in the middle of the box when that ball was played in. It was right out in the corner, it was drilled across and Klonaridis had all the time in the world. Somebody went to sleep in there.
