A very early chance for St Mirren as they win a free-kick deep in Rangers' half, with home striker Hamza Igamane picking up the first booking of the game.

Scott Tanser sends it towards the back post and it falls for Toyosi Olusanya in the box, but Rangers defend well.

An early chance for Celtic as captain for the day Alistair Johnson gets in behind and fires a low cross into the box that is cleared at the last second by Liam Gordon.

An early statement of intent from the visitors.

We're off at Fir Park and Ibrox.

Will Aberdeen still be out on their own at the top of the Premiership by the final whistles?

There's separate dedicated commentaries of both this afternoon's games via BBC Radio Scotland.

At Fir Park, former Celtic goalkeeper Pat Bonner and ex-Motherwell centre-half Stephen Craigan join commentator Stuart Mitchell.

Meanwhile, former Rangers and St Mirren striker Steven Thompson is with Thomas Duncan at Ibrox.

The teams are out at Fir Park and Ibrox. Healthy crowds at both - getting excited?

Motherwell manager Stuart Kettlewell tells Sportsound: "The main reason I've [handed first starts to a few players] is because they've been training really well, had good impacts in games they've come on in. They bring freshness, energy and pace - especially Marvin Kaleta.

"Tom Sparrow would've started last week were it not for a knock, so they've all earned the right and there's no pressure on them.

"We've been incredibly close to Celtic over the four games that I've been in charge. We want to be more than close, but we understand the size of the task.

"We've got the formula from those four games, but Celtic's changes today change it a little - no Callum McGregor for example - but we all know what they're about. I've got two or three things up my sleeve."

It's surely not often that a manager is handed a contract extension despite three straight defeats and one win in 11.

However, St Mirren showed their faith in Stephen Robinson in doing just that last week.

Nevertheless, his side head to Ibrox having not won in seven away games this season.

All of the stats - as well as the strength and cost of the respective squads - point to a home win here at Ibrox.

Of the last 24 league encounters between these sides, Rangers have won 22 and drawn the other two.

The last time the Buddies avoided defeat by the Ibrox men was Giovanni van Bronckhorst's last game in charge of them, a 1-1 draw in Paisley in November 2022.

There were a similarly weighty raft of statistics lining up against Motherwell when they came here at the beginning of March, but Stuart Kettlewell's men overturned them to win. A template for St Mirren today?

Celtic manager Brendan Rodgers tells Sportsound: "Callum [McGregor] felt a slight twinge after training yesterday. There's no need to make the risk. We've got more important games coming up, so we want to make sure he's right going forward.

"Everyone has seen the pride and joy Luke [McCowan] had of becoming a Celtic player. It always takes time to adapt to how we play and the intensity of our work, but when I've put him in, he's contributed.

"It's a nice start for him, he's a goal threat and he works hard so I'm happy to put him in."

Callum McGregor's absence with an abductor issue offers opportunity in the centre of the park for both sides.

For Celtic, Luke McCowan, Paulo Bernardo and Reo Hatate have a chance to showcase what they can offer as a trio, McCowan with his first start. A lot of Celtic fans have wanted to see him start given his cameo contributions so far.

For Motherwell, McGregor not being there might offer a touch more encouragement that they can impose themselves in that area.

These games can be tight. Motherwell have come close in them of late. It looks likely to follow a similar pattern.

Not surprisingly, there is more pressure on Rangers manager Philippe Clement than his St Mirren counterpart.

But some of that was eased after his side bounced back from last weekend's league defeat in Kilmarnock by sweeping aside FCSB in the Europa League.

The Belgian's side have lost at home to Lyon and Dynamo Kiev in Europe this season, but they have won all six domestic games at Ibrox, the latest five without conceding.

St Mirren's record against Rangers is equally as dismal as Motherwell's against Celtic.

The Ibrox side have won six in a row against their Paisley rivals, including all four meetings last season, with a combined score of 19-2 - the Buddies only scoring in one of those games.

Rangers have not lost in 13 meetings since a 3-2 League Cup defeat at St Mirren Park in December 2020 and have also won 13 in a row at Ibrox since a 1-1 draw in October 2011.

It is 24 meetings overall since the last St Mirren win at Ibrox, Kevin McGowne scoring the only goal of the game in November 1991.

St Mirren manager Stephen Robinson tells BBC Scotland: "You need to do the basics right to get anything out of a game at Rangers and that's first and foremost what I'm looking at.

"The performance, we're in control of, all the simple things in football. We're not in control of the referee's decisions or what Rangers do to an extent. If we control those, we've got an opportunity today.If we don't, we lose the game."

The one crumb of comfort for Motherwell is that Celtic have only won one of their latest four outings since their 7-1 Champions League thrashing by Borussia Dortmund.

A narrow victory away to Ross County has been followed by two draws.

In saying that, those were against in-form Aberdeen and then Wednesday's much-praised result away to Atalanta and Brendan Rodgers' side have won all four of their domestic games on the road, conceding just one goal on the way.

St Mirren manager Stephen Robinson says he's had to "strip everything back to the basics" this week to remind the squad of what they're good at and how they got into Europe last season.

Striker Kevin van Veen misses out today due to a foot injury that's not thought to be too serious.

Robinson is looking for a massively improved performance after the shocker against Hearts at Tynecastle last week, but St Mirren haven't won here since 1991, when the respective managers were Walter Smith and Davie Hay.

Rangers manager Philippe Clement tells BBC Scotland: "We will play more games than ever in the history of football this season so we need to make more and more changes.

"We need two, even three players, in each position to be ready all the time.

"I want to see a lot of hunger and desire to continue what they did on Thursday, against a different kind of opponent of course."

Rangers manager Philippe Clement tells me that Tom Lawrence's injury isn't as bad as first feared, but he still doesn't know when the midfielder might be fit to play again after picking up a knee problem in the win over FCSB.

John Souttar is rested due to the number of games he's played recently - the medical staff told the manager there was a risk of the centre-half picking up another injury if he played him today.

Motherwell make two changes from their defeat by Dundee last time out, with on-loan Wolverhampton Wanderers 20-year-old Marvin Kaleta handed a first start and being joined in midfield by Tom Sparrow.

They replace defender Dan Casey and striker Zach Robinson, who both make the bench.

As mentioned earlier, Callum McGregor is missing from the Celtic squad, with right-back Alistair Johnston captaining the visitors in the former Scotland international's absence.

Luke McCowan, who makes his first start since arriving from Dundee, and Paulo Bernardo replace McGregor and Arne Engels in midfield, with the latter dropping to the bench despite manager Brendan Rodgers defending the Belgian's recent displays in his pre-match media conference.

James Forrest replaces Nicolas Kuhn on the wing, while Kyogo Furuhashi is up front in place of Adam Idah.

Defender Cameron Carter-Vickers and Greg Taylor join Idah and Kuhn on the bench after recovering from injury.

Although Motherwell have come away with a draw on their latest two trips to Celtic Park, it is a different story at Fir Park, where today's visitors have won on their latest nine visits, scoring 30 times in the process.

Indeed, Celtic have not lost in 18 visits since a 3-1 defeat in April 2013 and Well have not enjoyed a victory over the Glasgow side in 31 meetings since a 2-1 league success at Celtic Park in December 2015.

To make an upset even more unlikely, Stuart Kettlewell's team lost last time out at home to Dundee as their seven-game unbeaten run - and three-game winning streak - on their own ground came to an end.
