Right now, Arne Slot won't suffer what Klopp had to go through when he joined Liverpool. There are players already in the team that can be a good start for him if he uses their talent well to his advantage. Liverpool still has Salah, Nunes, and many other players that are ready for the next season. We might be shocked that in his debut season, the club will extremely well more than previous season when we the fans are expecting to see a decline in performance.
Yes, at least currently Liverpool still maintains its talented players so that is an advantage for Arne Slot in building Liverpool's performance, there is no need to fight from the bottom because these players are experienced enough in their respective positions. Maybe there is only a slight difference regarding the strategy used by Arne Slot but sooner or later the players will understand it.
But regarding the results, we all don't know yet because the new coach has not guaranteed anything.
