AC Milan loanee Diego Laxalt makes his debut at left-back, having been preferred to Greg Taylor, who is among the substitutes.

Striker Patryk Klimala is handed just a second start of the season - partnering Mohamed Elyounoussi in a front two - as Odsonne Edouard fails to make the squad, having only returned from France on Friday following his positive test and quarantine.

Skipper Scott Brown is restored to midfield, with David Turnbull dropping to the bench as Celtic make four changes from their 2-0 win at St Johnstone a fortnight ago.

Former Celtic midfielder Si Ferry and ex-Rangers utility man Andy Halliday tell Connie McLaughlin they think the Old Firm match is "the biggest derby in the world".

Agree? Thumbs up for yes, thumbs down for no!

You can watch the full interviews on Football Focus from 12:00 on BBC One, iPlayer and BBC Sport website and app.

There are not too many surprises in the Rangers line-up, although the experience of veteran Allan McGregor is preferred between the sticks as Jon McLaughlin drops to the bench.

Ryan Jack will be a miss as the Scotland midfielder is also among the substitutes, but he did play twice in a week for his country having just returned from a calf injury.

Northern Ireland's Steven Davis slots into his place in midfield from the win over Ross County, with Filip Helander returning at centre-back in place of Leon Balogun and Brandon Barker playing as one of the inside forwards, rather than Jordan Jones.

A big boost for Rangers is the return of midfielder Joe Aribo, who is also among the substitutes.

Tom English argues that, whether it's "a barn-busting classic or a dreary stalemate", it will go down in history as the first, and hopefully last coronavirus derby between the two Glasgow behemoths.

Read his whole preview here.

While Rangers' selection headache revolved around who came back from playing for their countries without an injury, the big question mark for Celtic was how many of their four players forced to self-isolate while on international duty will be cleared to play.

Celtic manager Neil Lennon had claimed that Arsenal had been given permission to play Kieran Tierney against Manchester City today and therefore Scotland team-mate Ryan Christie ought to be able to face Rangers.

However, the Scottish government last night reaffirmed its position that anyone coming into close contact with someone who has tested positive for coronavirus, will be asked to self-isolate immediately for 14 days. Therefore, you imagine both should not be able to play today as Tierney should not have travelled out of Scotland.

France Under-21 striker Odsonne Edouard's self-isolation ended yesterday, so his participation depends on fitness, but Israel defenders Nir Bitton and Hatem Abd Elhamed definitely miss out.

Before concentrating on that early kick-off in the east end of Glasgow, here's a reminder of this afternoon's top-flight fixtures, with Dundee United's home game against fourth-placed Aberdeen catching the eye.

Meanwhile, third-top Hibernian will hope to take advantage if the top two share the points earlier when they travel to face Ross County.

It took a long time to get here amid the pandemic, but at last we have an almost full card of Scottish football fixtures - and with the long-awaited first Old Firm derby of the season topping the bill.

But first up at 12:30 BST is that big game at the top of the Premiership, with Neil Lennon's champions, Celtic, entertaining Steven Gerrard's leaders, Rangers.
