Rangers look set to return to a 4-3-3 system to face rivals Celtic - amid fitness concerns for defenders Clint Hill and captain Lee Wallace.
Rangers manager Mark Warburton is hopeful that recent injuries to two of his key defenders, Clint Hill and Lee Wallace, will not rule the duo out of the Old Firm derby clash this Saturday lunchtime.
However, the likelihood is that 38-year-old Hill is favourite to return from his dead leg, which forced him off in the second half of Rangers' 1-1 draw with St Johnstone, rather than captain Wallace - who missed out completely following a hamstring injury.
Against St Johnstone, Warburton accounted for the absence of his hamstrung left back by switching to a three-man back line. However, it is fully expected that against Celtic we will see a return to the more accustomed 4-3-3 set up, particularly in light of Hill's doubts and the attacking threat posed by the Scottish Premiership leaders.
Brendan Rodgers' Celtic are 16 points ahead of their Glasgow neighbours and are unbeaten in all domestic fixtures this season - including a 5-1 defeat of Rangers in the reverse fixture earlier in the campaign.
Although, this will not deter any Rangers fan or player ahead of one of the world's most famous derby meetings, as this fixture's history sways in Rangers' favour.
From the 152 Ibrox league games between the sides, regardless of whatever guise Rangers present, the blue side of Glasgow have won 72 compared to Celtic's 35 and the 42 occurrences of draws.
In an attempt to rectify September's 5-1 loss to the Hoops, Warburton looks set to name goalkeeper Wes Foderingham behind a back four of James Tavernier, Rob Kiernan and in the possible absences of Hill and Wallace, central defender Danny Wilson and Lee Hodson at left back.
Andy Halliday is expected to anchor a midfield trio alongside Jason Holt and Josh Windass, whilst supporting roles to front man Joe Garner look set to be afforded to Harry Forrester and Barrie McKay.
