Ryan Jack returns from injury for Rangers ahead of the Europa League clash with Porto this evening.
And the midfielder could have a key role to play if, as expected, he is selected to sit in the holding role in the Estádio do Dragão where he will likely face Colombian enforcer Mateus Uribe.
Andy King misses out for Rangers with a minor muscle injury but could return for the weekend clash with Motherwell. The only other absentee is winger Jordan Jones, who is two weeks away from a comeback from a knee injury.
Steven Gerrard is eager for his side to take something from the match having lost late on in the matchday two trip to Young Boys in Switzerland. He faces key decisions over whether to stick with Glen Kamara or bring back Jack while Joe Aribo could be under threat from Greg Stewart in the advanced midfield role.
Porto are full of danger and Ze Luis has hit the ground running at the Estadio do Dragao since joining from Spartak Moscow in the summer.
The Cape Verde international is level with Benfica's Pizzi at the top of the Primeira Liga scoring charts after netting six league goals in seven games.
Rangers were able to keep him quiet when they faced his former club Spartak in this competition last year and nullifying his threat again will surely be pretty high up on Gerrard's priority list this evening.
