This is the curveball in their plan really. If in the process of the natural ebbs and flows they have (which really emulates the stock market) is what happens when a dip comes. In football fans are a bit dim and don't see the bigger picture. This is amplified multiple times over by them, who are amongst the most stupid football fans you'll ever meet. What it can lead to is that a dip ends up become a spiral that engulfs the club.
Trying to pur rivalry aside for a moment, but I always think when they are on song they do very well. When it's smooth they amplify momentum well with their often ludicrous world view. However its no coincidence when things start to go wrong, it collapses quickly. You think of Souness, when Benitez went from being title challengers and within 18 months they were bottom of the league etc. To a degree even Rodgers, who was lucky the season ended the game he was 5-0 down after half an hour at Stoke.
I'd also add, if you want a calming presence at the helm to manage that dip, it's not Klopp.
