This was hammered home during Saturday’s 3-3 draw with Watford, with their lack of defensive stability in particular highlighting the need to add another centre-back.
“We are still working on all parts. We cannot build them. We have to have talks, we’re looking at all parts of the team,” he explained.
“The squad at the moment is not too wide for a lot of games because decisive players are not available. But that’s our situation.
“Yes, we did wrong [against Watford], and what do I want to do to sort it?
“People will say I need to buy a new player in the position. I don’t know if that makes real sense.
“We did well in the pre-season in this situation. We conceded goals, but we also did good things.
“We can’t only focus on one thing, but we know it’s an important thing, of course.
“I don’t feel comfortable because I can’t change it at the moment. But I know what to do.”
But Klopp is also looking to add to his midfield ranks before the end of the transfer window, as he revealed on Friday.
“We don’t have too many midfield players in the moment who have experience,” he said.
“Are we looking still for players? Yes. That is the truth. But we were looking for players before Adam was injured. Now he is injured and Phil is injured so we have two less.
“It doesn’t make the situation more comfortable. You cannot be really prepared for situations like this but we have time.
“Everything can happen. But I’m not sure that they will happen. If I were sure, they would probably already be in or whatever. It’s still open for business.”
