Daizen Maeda, that needs to be better.

Alistair Johnston sends him over the top and the Japan forward races into the box.

But he's hesitant and in the end his lofted attempt doesn't do enough to trouble the keeper.

Looks offside on the replay actually.

Matt O'Riley almost pulls off a stunning pass to play in Yang, but Alessio Romagnoli just gets there.

An attack breaks down between Kyogo and Yang and Lazio are off in a flash.

It comes to nothing for them as well though. Celtic living dangerously at times.

Kamada is always stretching, why's he going for it at all?

Felipe Anderson was coming in behind him.

Greg Taylor gets the ball nicked off him far too easily and now there's a huge gap on Celtic's left.

The ball is slipped in for Daichi Kamada, but he can't find a Lazio shirt in the box.

More like it from Celtic.

This time Kyogo pops one off for Matt O'Riley to strike from the left of the box.

Ivan Provedel does well to hold it though.

Yang does well to skip his way to the bye-line, but his cross is hacked away.

Celtic win the ball back within seconds. They're getting proper encouragement from their packed home crowd.

Celtic have lost their way a little bit, Lazio are now in control.

Like a popped party balloon, a previously energised Celtic Park has fallen flat after the home side were undone by a couple of Lazio corners.

It's the visiting fans literally banging the drum now, encouraged by the equaliser.

Celtic may have not been keeping a close eye on the ball in the box, but one of the Parkhead faithful certainly is.

Probably needed them to see if the ball was over the line there.

That goal seems to have sparked Celtic back into life.

Greg Taylor wants a penalty for handball as his cross is blocked.

Nae chance.

It's clearly over the line. A valiant effort from Joe Hart to save it.

Celtic don't react to the second ball and Vecino can just head it in.

They will be disappointed to have conceded again from a set piece, they've got to keep going and regroup.

Brilliant tracking back from Daizen Maeda, who slides in on Elseid Hysaj.

It's a Lazio corner though, which Alistair Johnston heads behind at the back post.

Lazio are cranking it up.

Liam Scales has certainly be tuned in so far, Pat. Oh, forget that. He's just passed straight to a Lazio shirt.

The ball is dinked over the Celtic defence beautifully and Ciro Immobile forces Joe Hart down to his left to save a volley brilliantly.

Up goes the flag anyway.

Lazio are targeting the left-hand side of the Celtic defence.

Greg Taylor and Liam Scales ought to remain tuned in so they don't get caught ball watching.

Maurizio Sarri's not cutting a happy figure at all.

After the latest Lazio pass goes astray for a Celtic goal-kick, he throws his arms up in the air and retreats to the dug-out in disgust.

A man under pressure after only two wins so far this season? Not his night so far, that's for sure.

Lazio are showing signs of getting at the Celtic defence, but it just isn't falling for them at present as Daichi Kamada is done for a handbaw.

Quite surprised to find out that's Kyogo's first Champions League goal.

Was certain he had scored last season as well.

Not a bad time to get it.
