Steven Gerrard’s men head into this game on the back of three defeats in their last four matches across all competitions.
They will have to improve their performance to grind out a positive result here.
Alashkert are also in poor form, having won just one of their last four games, but will fancy their chances of upsetting the odds.
Rangers are the favourites but must guard against complacency.
Ryan Jack is injured, while Kemar Roofe and Glen Kamara will miss the game due to suspension.
Gerrard will likely make seven changes to the side that won 5-0 against Dunfermline over the weekend.
John Lundstram is amongst the players who will miss out, but Alfredo Morelos is set to return to the starting line-up for the crunch clash.
Rangers Predicted XI (4-3-3): Allan McGregor (GK); Borna Barisic, Leon Balogun, Connor Goldson, James Tavernier; Joe Aribo, Steven Davis, Scott Wright; Ryan Kent, Alfredo Morelos, Ianis Hagi.
Alashkert Predicted XI (4-3-3): Ognjen Cancerevic (GK); Dejan Boljevic, Tiago Cameta, Taron Voskanyan, Didier Kadio; Artak Yedigaryan, Rumyan Hovsepyan, Artak Grigoryan; Jose Embalo, Aleksandar Glisic, David Khurtsidze.
