An excellent challenge from Filip Helander inside his own six-yard box sets up a Rangers breakaway.

Alfredo Morelos evades a challenge and drives a cross across the face of goal. There are no takers before Borna Barisis blazes over at the back post under pressure.

End-to-end stuff already.

St Mirren's Premiership match against Motherwell has been postponed after another of the Paisley's club's first-team players tested positive for Covid-19.

St Mirren say "a number of additional players" are now required to self-isolate.

As a result, they informed the SPFL they could not fulfil Saturday's fixture.

On-loan AC Milan left-back Diego Laxalt's first involvement is a crunching tackle on James Tavernier.

The Rangers right-back picks himself up and flights in a dangerous free-kick that Celtic scramble clear.

Rangers get the game under way looking to stay top of the Premiership.

A unusual Celtic line-up is aiming to overtake their rivals with a game in hand.

The tannoy belts out the Celtic players to welcome the players.

No sing-a-long from the stands, but it's still massively important to supporters from both clubs around the world.

Celtic manager Neil Lennon is a veteran of these fixtures, but the big difference this year is the lack of fans.

"You miss the build-up and driving in to the stadium when there's people lining the streets waiting for you to come in," he tells BBC Scotland's Sportsound.

On picking Stephen Welsh and Patryk Klimala, Lennon said: "It's great, you don't get much time to think about it. He [Welsh] trains with us every day, he's part of the squad and never let us down, so no problem playing him.

"[Patryk] Klimala is hungry. What these two will give us is an effervescence, a hunger and desire which has maybe been lacking in some areas."

Asked if he was annoyed about his team being leaked on social media last night, Lennon added: "You have no idea. But I don't want to comment on it now."

A few minutes away from kick-off. Hope you can feel the excitement building despite the lack of fan atmosphere at Celtic Park.

Indeed, I hope you are taking First Minister Nicola Sturgeon's advice and not gathering in big groups at home or travelling to pubs in England to watch it on TV!

Rangers manager Steven Gerrard has urged his side to replicate the performance that secured a 2-1 win at Celtic Park when the sides last met 10 months ago.

"We come here in a different place than when I first took charge," Gerrard told Sky Sports.

"You could see a bit of fear because we had been on the receiving end of some really bad results in this fixture, but we can now tap into recent performances against Celtic.

"I have told the players to go and express themselves and believe in themselves. We did it last year because to a man we carried out a gameplan and we need to do the same today."

Rangers' December win at Celtic Park ended a run of three defeats there.

The two sides have alternated between victory and defeat in their last six league meetings.

But Rangers haven't won back-to-back Old Firm league games since October 2009 and last won two in a row at Celtic Park in March 1997.

It is a match-up between two sides who have become goalscoring and winning machines, domestically and also in Europe.

Celtic are seeking a ninth consecutive victory and their fourth on their own patch, while Rangers are unbeaten in their most recent 12 games, including all seven away from home.

Today's hosts have scored three goals in all three of their home league matches this season. The visitors have found the net 18 times in their latest five games away from Ibrox.

Chances are it's going to be a high-scoring game then? Think again - Celtic have not conceded in four games while Rangers have only been breached three times in 10 league games so far.

Ianis Hagi is on Rangers' bench, which is a bit of a surprise given his creative influence.

The 21-year-old Romanian midfielder has been involved in nine goals for his side since arriving, initially on loan, in February - three more than any other player in the Ibrox squad. He has assisted in three of Rangers' last four goals in open play.

In contrast, while Alfredo Morelos has returned from international duty with an assist of his own in Colombia's draw with Chile, the striker has still not found the net against Celtic in 10 outings against the Scottish champions.

Odsonne Edouard's exclusion could be significant given the French striker's record against Rangers.

Only against Motherwell has the 22-year-old scored more than the six goals he has fired against Celtic's city rivals.

In his four league appearances at Celtic Park against today's visitors, he has been involved in six goals - scoring four and setting up the others.

Rangers won 2-1 on their last visit to Celtic Park in December, Nikola Katic, who has been injured for much of this season, heading the Ibrox side's winner after host striker Odsonne Edouard had cancelled out Ryan Kent's opener.

That narrowed the gap to two points with a game in hand going into the winter break, but Rangers' season fell apart after that and Celtic were named champions when Covid-19 pandemic ended the season prematurely.

This time, Rangers can little afford to lose as they attempt to prevent Celtic securing a historic 10th title in a row. A Celtic win would put Neil Lennon's side two points clear at the top with a game in hand.

John Beaton is taking charge of his first Old Firm game since being targeted with death threats and online abuse in December 2018.

Celtic had called for the referee to be allowed to explain his decisions publicly after he did not punish striker Alfredo Morelos for clashes with Anthony Ralston, Ryan Christie and Scott Brown during a 1-0 win for the Ibrox side.

Let's hope Beaton enjoys a less stormy, controversy free 90 minutes this time.
