Having scored his first goal for Rangers, Ryan Jack thinks he is about to deliver his second.
However, Celtic goalkeeper Craig Gordon produces yet another brilliant save, diving low to turn it away one-handed.
Rangers 1-0 Celtic
Celtic have substitute Anthony Ralston to thank for not going further behind.
James Tavernier breaks into the penalty box and his cut back is cleared in front of his own goal by the opposing right-back under pressure from Ryan Kent.

Quote MessageI can't believe what I'm watching. Craig Gordon came up with a big save to keep them in the match. If Celtic get out of this, especially now with the changes forced upon them, it will be really something
Rangers 1-0 Celtic
Celtic quickly race to the other end and Ryan Christie fires low and wide from the edge of the penalty box.
Rangers 1-0 Celtic
Rangers should increase their lead.
Dedryck Boyata is robbed by Ryan Kent after collecting from Craig Gordon.
The winger is through on goal, but goalkeeper Gordon saves superbly, diving low and, when Kent plays it to Alfredo Morelos in front of goal, it bobbles to Scott Arfield.
It looks the midfielder's low shot is heading for goal until Boyata redeems himself by clearing off the line.
Rangers 1-0 Celtic
We're up and running again at Ibrox.
Celtic make a second defensive substitution, with Anthony Ralston on for Mikael Lustig.

Quote MessageThe first thing you have to do in an Old Firm game is win the battle. Celtic have been so passive, every 50/50, every second ball. One team want to win today. Rangers have blown them away - it's been no contest.

Rangers are unbeaten in the league this season when when they have scored first.
Celtic haven't won after conceding the first goal.
Ominous for Brendan Rodgers' side?

HT: Rangers 1-0 Celtic
It's been a game of square pegs in round holes, with Rangers successes and Celtic failures.
Andy Halliday has been no stranger to being played at left-back but has had his troubles there in the past. However, the midfielder has been calm and assured.
Callum McGregor has been asked to make a similar switch for Celtic, but the Scotland midfielder has been under constant pressure.
Meanwhile, Mikey Johnston has been asked to play on his own up front instead of Odsonne Edouard, but the 19-year-old winger has been anonymous.

Quote MessageIt's been a horsing. Rangers have been outstanding. Celtic have made mistakes, Brown making mistakes, Benkovic making mistakes, but they're being forced into that by Rangers' intensity, which has been phenomenal

Quote MessageRangers leading the derby and it's thoroughly deserved, the way they've gone about their business here today
Rangers have earned their half-time lead with a performance built on hustling and harrying their opponents all over the pitch.
The midfield three of Ross McCrorie, Scott Arfield and Ryan Jack have been pivotal to that, with the latter providing the cutting edge with the game's only goal after good build-up play by Ryan Kent.
The question for the second half is whether or not Rangers can maintain this work rate - and if Celtic can utilise the strength of their bench.

Rangers' turn to have an injury as Daniel Candeias goes down clutching his shoulder after a collision with Mikael Lustig that results in a booking for the right-back.

Quote MessageThis is a substitution I'd be tempted to make anyway - Benkovic has had an absolute shocker. But that's one less change now that Rodgers can make to put things right here
Rangers 1-0 Celtic
Filip Benkovic pulls up when making a pass back to goalkeeper Craig Gordon in stoppage time.
The on-loan Leicester centre-half is replaced with Kristoffer Ajer.

Quote MessageFascinating to see Rangers hustling and harrying Celtic into mistake after mistake. No threat whatsoever from the champions. Rangers could/should be three ahead. Intriguing second half coming up. Rodgers has to get Odsonne Edouard on and Callum McGregor into midfield

Quote MessageI would say this is Rangers' best performance of the season - they have been outstanding to a man. Celtic, on the other hand, I've not seen them this poor or rattled. Rodgers can't wait for half-time
