Jurgen Klopp says he has no plans to reintroduce Joe Gomez and Virgil van Dijk back into the Liverpool side that plays Hertha Berlin next week.
Neither player was risked on Friday evening as the Reds beat Mainz 1-0 in their third game of the pre-season tour of Austria.
Ibrahima Konate partnered Joel Matip for the first half before a fully-changed side had Nat Phillips and Billy Koumetio at the back.
Asked if either Van Dijk or Gomez would be ready for Thursday's game with the German side, Klopp said he would remain patient with his two defenders as they continue their respective recoveries from season-ending injuries.
"Yes, I would be still surprised [if they played on Thursday], unfortunately," Klopp told LFCTV.
"But they look really good, it's just, look, they play football, we keep them in training, we do the things we can do, we just have to be patient.
"We have them for a full season and not [just] for a pre-season game. So I will not risk it for a game, we will have to see.
"We have a lot of pre-season games coming up but I don't see them being involved for the next one."
Owen Beck's cross was turned into his own net by Luca Kilian late on to give the Reds their first win of pre-season so far and Klopp was pleased with what he saw, but described it as understandably "far from perfect" at this stage of the summer calendar.
He added: "We always consider what we did the day before and had a double session yesterday, we trained this morning and that's exactly what you need and that is how training works, actually.
"You have to do intensive stuff, go through it and try to play the best football you can.
"It's the pre-season, I am happy about a lot of situations and I saw a lot of stuff, good football, where we passed and the ball was moved quickly against a well organised side who defend deep and all this kind of stuff.
"It was far away from being perfect, but it is absolutely OK. And in the second half I saw that the kids fought for a result, they got it and they forced it, so it was good.
"Organisation-wise, it is not even close to where we want to be, but when you are tired, you try to bring the best organisation on the pitch.
"So it is not about being 100 per cent, it is about being available to get to 100 per cent and I think the boys did that today.
"Nobody was injured, everyone came through, so I am really fine with this."
