Joe Hart is out at the edge of his box again but only prods nervously at the ball when a big hoof is probably the best option.
Rabbi Matondo is first to it but blazes high and wide of the empty goal from 30 yards or so.
Rangers 0-0 Celtic
A bit of a lull in play as the tempo drops... The stadium is still abuzz from the fall-out after that disallowed goal.

That disallowed goal is a big lesson for Gustaf Lagerbielke.
Do not hesitate on the ball, do things quickly, get the ball away, you'll be put under pressure.
Rangers 0-0 Celtic
Cyriel Dessers is away again as Ranger launch yet another pass over the top. Joe Hart beats him to the ball at the edge of this area - but only just.

That moment is going to be the talk of the town tonight.
There's contact but is it a foul?
It is an incredible let off for Celtic and Lagerbiekle in particular.

Wow, wow, wow.
That's not a free-kick for me. Lagerbielke has kicked Dessers!

To me, Lagerbielke just doesn't look strong enough. I really don't see a foul here.
There's not a Rangers fan in here that will think that's a foul.
Rangers 0-0 Celtic
Oh my. The ref rules that there was indeed a trip on Lagerbielke.
That looks very, very soft.

Oh hang on, Don Robertson has been asked to check the monitor.
Was there a foul on Lagerbielke by Dessers?
Kemar Roofe
Gustaf Lagerbielke is overpowered by Cyriel Dessers and the big striker races away to square for Kemar Roofe to slam home.
Joe Hart is dragged wide and is scampering back as the shot whistles through his hands.

The keeper makes himself big enough. I think that's what stops Kyogo.
This game is livening up now. The chances are starting to come.

You would have put you house on Kyogo scoring. What a chance!
Celtic are pressing so well, Souttar got caught out there with the ball beneath his feet.

Defensive heroics from Connor Goldson!
Kyogo is one-on-one and squeezes his shot past Jack Butland but the Rangers centre-half slides in to save the day with his backside.
Rangers 0-0 Celtic
Pat Bonner
Former Celtic goalkeeper on BBC Sportsound
Kyogo is playing higher than he has in the last couple of games... I think Celtic have been working on that.
They're playing with a high intensity, and they're in a good position doing so.

Sitting directly behind the Celtic bench, I keep catching the look on new signing Luis Palma's face watching on.
He's wide-eyed taking this all in, the pace and intensity that always comes with this contest.
He may play a part as this progresses.
Rangers 0-0 Celtic
Cyriel Dessers goes too early again, although even from an offside start he can't quite reach a low cross from Rangers skipper James Tavernier.
Rangers 0-0 Celtic
Pat Bonner
Former Celtic goalkeeper on BBC Sportsound
He's got to score!
McGregor opening things up as he does in the middle of the park, and what a brilliantly weighted pass for Abada.
It's the best chance of the game.
Rangers 0-0 Celtic
What a chance for Kyogo to open the scoring!
Liel Abada gathers a lovely ball in behind from Callum McGregor and zips in an inviting cross, but the Celtic striker can't make a clean connection in front of goal, trying to go for a wee flick six yards out.
Rangers 0-0 Celtic
Neil McCann
Former Rangers winger on BBC Sportsound
Rangers are starting to dominate the ball and possession and they're beginning to ask questions of this Celtic midfield.
