Liverpool will be looking to make it two wins in a row in Europe when they host Rangers in Group A of the Champions League on Tuesday.
The visitors have lost both of their opening matches so can ill afford another defeat if they are to remain in the competition.
Scotland left-back Andy Robertson, who grew up supporting Rangers’ fiercest rivals Celtic, will miss out on Tuesday’s tie with a knee issue, but he could make a return to Liverpool’s squad for the weekend’s trip to Arsenal.
Likewise, Ibrahima Konate is back in training but was absent from the Reds’ matchday squad against Brighton, and the France centre-back may be saved at this early stage of his recovery from a knee injury.
Naby Keita and Alex Oxlade-Chamberlain remain long-term absentees, hence their exclusion from Liverpool’s Champions League squad, while Curtis Jones, Calvin Ramsay, Kaide Gordon and Caoimhin Kelleher are still expected to be sidelined.
Klopp is likely to make at least a few changes to his starting XI from the weekend, with Luis Diaz, Darwin Nunez, Diogo Jota and Harvey Elliott all providing offensive options to freshen things up in what is set to be an extremely busy October for the 2018-19 European champions.
Rangers will travel without Sands, who must serve a one-match suspension following his dismissal against Napoli, with former Liverpool centre-back Ben Davies likely to partner Connor Goldson at the heart of the defence.
Morelos could replace Colak in attack in order to provide more industry and link-up play from that position, with Steven Davis likely to be called upon in midfield for his experience and calm head in possession.
John Souttar, Tom Lawrence, Filip Helander, Jon McLaughlin, Nnamadi Ofoborth, Ianis Hagi and Kemar Roofe are all unlikely to make the trip to Merseyside due to injury.
Liverpool possible starting lineup:
Alisson; Alexander-Arnold, Matip, Van Dijk, Tsimikas; Elliott, Henderson, Thiago; Salah, Jota, Diaz
Rangers possible starting lineup:
McGregor; Tavernier, Goldson, Davies, Barisic; Lundstram, Davis, Jack; Tillman, Morelos, Kent
We say: Liverpool 3-0 Rangers
