And they try to fashion that opportunity at the back post but James Tavernier's header doesn't result in a chance.

Rangers are rocked, there's no doubt.
They just have to regroup and try and make a couple of passes.
They need to fashion an opportunity to show Celtic they're not done yet.

Matt O'Riley is back on with a fresh top.

Matt O'Riley is going to have to come off temporarily.
Celtic are down to 10 for now.

Accidental.

Kyogo Furuhashi has scored five goals in last four league starts against Rangers.
Ruthless.

Celtic have started this second half so, so well.
They're all over Rangers.

The two goals Celtic have scored have been of the highest quality.
When he shifted it to his left, I thought it would be a tough one to beat Jack Butland from there.
He leaves him flailing. What a finish.

Kyogo Furuhashi goes for goal and he hits it so sweetly up into the top left-hand corner.
The goalkeeper had no chance whatsoever, it was a brilliant strike.

What a goal. That is an absolute cracker.
Kyogo has two players in front of him, but he just drops his shoulder. That was out of this world.
Kyogo Furuhashi
Goodness me. He's done it again.
Matt O'Riley turns beautifully in midfield and pings a pass into Kyogo.
You can hear Celtic Park screaming for him to slip Daizen Maeda in but his mate has other ideas.
Kyogo shifts it on to his left foot and curls an absolutely beauty into the top-right bin.
What a goal.
Celtic 1-0 Rangers
Right, so we've had some guidance on the penalty.
We're being told there was an offside offence against Abdallah Sima as the ball was played in, before it struck Alistair Johnston's hand.
Regardless, the officials apparently deemed the movement of his hand to be natural.

We're back under way at Celtic Park.

Rangers must be quite pleased that they've got into good areas, they have broken well in the last 10-15 minutes and they have had chances - and that penalty claim on top of it.
And you can feel around the stadium - there is more uncertainty than there was beforehand.
Usual Celtic-Rangers game. Ebbs and flows, 100 miles an hour, great entertainment.

I think it should have been a penalty. Johnston's right hand catches the ball, he knocks it out with his hand in the penalty area.
He doesn't mean to do it, but his hand makes contact with the ball. For me, it's a penalty.

I don't think it was deliberate, I don't think he has made his body unnaturally bigger.
Alistair Johnston just gets his bearings all wrong. For me, he has not deliberately handled it and I think the officials will look at it the same way.

So what are the pundits saying?
Former Rangers striker Kris Boyd says "it's a penalty all day long" - that probably won't come as a surprise to many.
But ex-Celtic boss Neil Lennon says he would be "apoplectic" if that wasn't given for his team.
