Klopp admits they need to find a way to grind out results after defeat to Fulham on Sunday.
He explained, "In the game, the reaction football-wise was kind of OK. We obviously have a lot of players who stand for mentality not on the pitch in the moment, who can be like a leader in these moments and stuff like that. That's clear. Again, I try to answer all the questions, the thing is just we got that many knocks; you can want to win a game because you won all the others before, or you want to win a game because it is a while ago that you won a game, that is more our situation.
"Believe me, these boys want [it] but it doesn't work in the moment and there are some reasons for it: we don't score goals and we concede at least one, which in the moment looks like it is enough against us. You can discuss whatever you want, obviously, I cannot just answer and say, 'Yeah, we don't have mentality.' We have mentality, it's just not the mentality we are used to probably, but the boys want to win games."
Klopp admits individual errors are also hurting them.
He continued: "They wanted to win this game today. I saw that. We made mistakes still, that's the problem, but that's not about you don't want it - the boys don't want to make mistakes, we just made them. We have to make sure the mistakes we make are not accountable anymore, so like you can concede a goal - we conceded goals in our best phases, the best periods of our lives, but the only thing is then you are not bothered about it.
"That's where we have to come. We have really tight results in the moment, pretty much always against us, and we have to make sure we win football games again. If it's a 1-0, it's fine, fight for it with all you have and then you can gain confidence and momentum maybe again. In the moment we don't have that."
