The German goalkeeper signed for the Reds from Mainz during the summer, to provide competition for Simon Mignolet, but suffered a broken hand in pre-season.
Karius made his return from the injury in the midweek EFL Cup win over Derby County which has prompted Klopp to hint that he could keep his place in the line-up, even if it was a cryptic response when quizzed on who is indeed his number one goalkeeper.
Klopp said: "Let's go through a few different kinds of ways in which we could see it.
"Do we say, 'Okay, Loris had the game against Derby. Was it a real game for a keeper? Not really. So give him a home game' for example.
"What would this mean for Simon? Or it could mean nothing.
"We could say, 'There is an international break coming up, so give Loris a home game and Swansea away' and then both have had the chance to show what they are.
"It's not in doubt, it's not a test.
"I accept again the circumstances over the keeper's position. But in the end it's 100% positive — Liverpool FC will have a very strong goalkeeper on Saturday between the posts."
