As Doomloop observed, Liverpool just changed their coach, you don't expect them to continue with the momentum of Klopp. It is possible that the momentum could and if care not taken, drop low before they could rise again.
Jurgen Klopp did his best for Liverpool, atleast we've watched him lifting major trophies with Liverpool and also helping them becoming one of the top fierce EPL elite team in the world of European football.
Liverpool new coach, Arne Slot will be one of the promising coach for Liverpool but all he needs is patience because he's new to Liverpool system and the new coach have his own style to implement.
