I can't help feel that we shouldn't go back. I think the issue is we are missing all of the things that Klopp did give us, the unity, the fight, etc. We lack that at the moment. That said, Klopp was not without his flaws and he could be frustrating, many of the issues now with Slot's team were all too apparent when Klopp was here, particularly relating to the highline and how badly it is getting more and more exposed. His blind spot with Trent, and so on.
Would he be as good now? Who knows, but we need to think about someone who has the potential to have longevity with us, we like dynasty's and we have a certain "type" that have to understand the Liverpool way and the class associated with it. Slot has said some good things along the way, but it's almost scripted, when he's had to talk about difficult subjects surrounding the team and it's individual performers, he's smacked of someone who is well out of his depth. Rafa and Klopp had that air of class about them (not to say they didn't have their moments with players, but generally they exuded class).
