Striker Toyosi Olusanya goes down inside the Rangers box, but the penalty shout is waved away by VAR.

They do have a free-kick, though, but Mark O'Hara sends it way over the crossbar.

Motherwell look to the bench to try and change this game. Andy Halliday, Davor Zdravkovski, and Apostolos Stamatelopoulos off.

Tawanda Maswanhise, Zach Robinson and former Celtic striker Tony Watt on.

Here comes Rangers captain James Tavernier, with Robin Propper, who has been suspect at the heart of defence being the one to make way.

Neraysho Kasanwirjo goes to centre-back to allow Tavernier to slot into his usual right-back berth.

Midfielder Connor McMenamin is on for his first appearance of the season for St Mirren.

This one is coming to the boil nicely now.

The intensity is picking up from the home side at last, with better chances being created and Ellery Balcombe in the visiting goal getting busier.

The home fans are impatiently urging them on. Not sure how many of them were expecting to be at 1-1 after an hour?

And it could have been worse but for a more than decent save from Jack Butland to deny Toyosi Olusanya, who also missed a glaring first half chance at 0-0.

Nedim Bajrami plays a nice ball into the visiting penalty box and Cyriel Dessers gets a head to it, but once again Ellery Balcombe does his goalkeeping duties to keep out the hosts.

There is a check for a penalty at Ibrox as Greg Kiltie goes down, but no spot kick for the visitors. It did look soft.

Up the other end, goalkeeper Ellery Balcombe makes a great diving save to deny Rangers.

Deputising for injured captain Callum McGregor, Alistair Johnston has stepped up to find the crucial second and that will settle Celtic.

It affords Brendan Rodgers the chance to potentially make changes and that might bring even more threat given what they have on the bench.

The away crowd are loving this - even more so as Rangers continue to struggle at Ibrox.

They simply wore Motherwell down.

There was no pressure and nobody went to engage, so Celtic were allowed to just keep moving the ball at will.

Robin Propper stopped there when Toyosi Olusanya ran in on goal.

The Rangers centre-half was assuming - and certainly hoping - that the offside trap he had set had worked. Dangerous game.

The natives are getting a little more restless here, however, with too much of the game still being played in Rangers' own half for their liking. They need a spark from somewhere - or someone.

St Mirren sriker Toyosi Olusanya is one-on-one with Jack Butland and sends it beyond the Rangers goalkeeper before the flag is raised for offside.

Motherwell work a chance, but once again it's squandered.

Apostolos Stamatelopolous tries to volley a cross but slices it horribly.

Thankfully for the striker, it turns into a great pass to Ewan Wilson behind him, but the midfielder's volley is also pulled well wide.

Rangers supporters once again show their feelings towards the club's hierarchy with a banner.

A display with a similar sentiment was displayed at Rugby Park last weekend, when the side lost to Kilmarnock.

A better start to the second half from Rangers.

Mohamed Diomande gets the ball on the edge of the St Mirren box thanks to a decent pass from Vaclav Cerny, but the midfielder smacks his shot wide.

There's been an early second-half booking for Celtic midfielder Paulo Bernardo for a foul in the middle of the park.

Celtic almost find a second goal moments later.

Kyogo Furuhashi turns nicely on the edge of the box and cuts on to his right, drilling a shot at the near post, but goalkeeper Aston Oxborough is down well to save.

Here come the Rangers players at last - and there is a change at the break.

Cyriel Dessers is up front in place of Hamza Igamane, who was anonymous in the first half.

As things stand, Rangers are eight points behind Aberdeen and Celtic. After nine games.

That simply won't do around these parts, so there's a massive incentive for these Rangers players to up the ante, up the intensity levels and make sure no further points are spilled.

We're off at Fir Park, but no signs yet of the players again at Ibrox.

Home manager Philippe Clement could be giving the home side the verbals.

The intensity levels for Rangers are nowhere to be seen. It's been so, so poor.

You have to give St Mirren a massive amount of credit. They've been excellent and they started the game ever so well.

The fans are right to be booing the home side off the pitch. That is nowhere near the standard expected here at Rangers.

That's the problem for them the whole of the season - it's one good game, one bad game, one okay game, one bad game. They can't get a level of consistently good performance.
