Celtic 1-1 Lazio
Ahhh, that's some save!
Matt O'Riley shifts it to Reo Hatate, who drives one low to the bottom-right corner.
But Ivan Provedel gets down to parry it out of reach of Daizen Maeda.
Alistair Johnston then blasts over. He should probably do better with that.

Matt O'Riley and Reo Hatate are over this...
Celtic 1-1 Lazio
For the first time in a while, Celtic are enjoying a decent spell of possession.
It ends with Yang winning a free-kick in a very promising position after he shows great feet.
This is much better from the winger.

Celtic corner now after Kyogo's shot is blocked.
Matt O'Riley, what ye got? A floated ball to the back post to Nat Phillips, who nods into the six-yard box, but a foul is given.

It's not a bad cross but Kyogo just couldn't quite get on the end of it.
It's good pressure though from Celtic.
Celtic 1-1 Lazio
Daizen Maeda shows his blistering pace to get in on the right and his dinked cross looks to find Kyogo for a tap-in.
But Lazio centre-back Patric makes a crucial intervention with his head.

Where is the left of Celtic's defence?!
Felipe Anderson has the freedom of Parkhead and Ciro Immobile finds him on the right.
But the winger inexplicably tries to cut inside instead of shooting and the chance is gone.

Felipe Anderson looks lively this half as he flashes a wicked ball across Joe Hart's goal.
Celtic survive.
Celtic 1-1 Lazio
Lazio start the brighter as a searching diagonal ball finds Felipe Anderson on the right, but his cushioned volley into the box goes straight to Joe Hart.
Celtic 1-1 Lazio
We go again.

Yang has been in great positions, with great opportunities, but he's trying to force it a little.
He's making wrong decisions, trying to play that perfect pass. He's got the potential to do something, but it's just not quite coming off for him.

Former Celtic manager on TNT Sports
Celtic don't get first contact in the box [for Lazio's leveller] and then it becomes a 50/50.
Celtic had invited a little bit of pressure in the build-up, but they've played really well.
There are more goals in the game.

That pass from Matt O'Riley is exactly what you want from an attacking midfielder, there is nothing better.
If he keeps playing the way he is, he's going to keep being one of the first names on the team sheet.

Aye, it's completely unrelated to tonight's game, but is there ever a wrong time to watch Tam Rogic screamers?
With the news of the Australian's retirement this week, we got the spades oot and dug into the archives to make a montage of his best Celtic goals.
Certainly worse ways to spend the half-time break.

It was a fantastic start from Celtic, playing really good football too.
After that, though, Lazio came back into the game with the bus-stop corner routine and Celtic are undone with marking few and far between.
Celtic have played well, beaten the press well at times from Lazio, but they've also been guilty of giving them the ball back in their own final third.
Can someone tell me what a 'bus-stop corner routine' is?
HT: Celtic 1-1 Lazio
It's been a high-intensity game at Celtic Park, but the numbers tell us it's been a pretty uneventful one in front of goal so far.

There's one glaring weakness for Celtic so far.
Down their left-hand side, Yang has struggled to make any meaningful impact.
I wonder how long he'll last with Luis Palma waiting on the bench.

I think Brendan Rodgers will be happy. His team have played very well.
Agree, Celtic fans?
That was quick.
A breathless half at Celtic Park ends with Nat Phillips getting booked. I'll be honest, I don't really know why.
Anyway, this one is level at the break after Matias Vecino's deft header cancelled out Kyogo's opener.

Joe Hart decides to drop the heart of every Celtic fan with a wild attempt at a clearance.
Dearie me, anything could've come of that.
