Andrew Robertson and Dominik Szoboszlai have also been described as “touch and go” by the Liverpool manager but are thought to be closer to returns, the Scottish full-back having been an unused substitute in the midweek Carabao Cup tie at Fulham.
It is possible that Klopp opts to leave some or all of the returning trio on the bench to gradually reintroduce them ahead of facing Chelsea on Wednesday and a Premier League title showdown at Arsenal next weekend.
Joe Gomez and Conor Bradley have both impressed as full-backs of late so a decision will have to be made on how to accommodate them alongside Robertson and Alexander-Arnold.
The in-form Merseysiders also have plenty of competition to consider in the midfield, where Curtis Jones and teenager Bobby Clark are pushing to start.
Up front, Diogo Jota was on the bench at Fulham and could be rotated into the line-up.
Klopp may well opt for a strong starting line-up for the fourth-round tie to avoid an upset or unwanted replay, with the bench likely to feature several youngsters hoping for minutes late in the game.
