The Bundesliga giants have lost four of their opening seven league games this season, leaving them 10 points adrift of leaders and reigning champions Bayern Munich.
Klopp is quoted as saying by Goal.com: "If I lost the faith, which I have not, then it would be relatively difficult to deal with this situation. I have lost no fire.
"This is a phase for a coach, that is it, we have to work hard, it's as simple as that. We are moving closer together and will get out of this situation, we are all agreed on that.
"It's all there to turn now, we can only move forwards. It may indeed end up to be an extremely positive story."
