Amid an injury crisis in defence, the Premier League champions added Kabak, on loan from Schalke, and Davies at the end of the mid-season transfer window.
With Virgil van Dijk and Joe Gomez sidelined and Joel Matip set to miss the rest of the season, Liverpool will also be without Fabinho for Saturday's trip to Leicester City.
Kabak or Davies could debut at the King Power Stadium and Klopp said the pair were making strong progress.
"They are calm people, both Ben and Ozan, willing to learn, really great attitude," he said.
