I am sure that Liverpool will be fine, I cannot say if they are going to end up being in the title race again or not, but last season they were leading the league until a very last moment, then they lost points back to back after that Atalanta loss, I guess their morale just got destroyed after that, and they finished third because of the points lost on that period.
Will Arne Slott be similar to Klopp and keep the team going? Will he make them play a good football? I am not entirely sure and we are going to see, but until then I just assume that they are going to be a top four team no matter what since that's their level. Without that, if they finish worse, then I do not think that they are going to end up any good.
So far we have seen that Klopp is able to optimize the squad he has at both Dortmund and Liverpool to remain competitive as title contenders, so that is why he can become one of the best coaches ever, we don't know much about Arne Slot ability in coaching so far although he was able to handle Feyenoord well previously, but now we are talking about the Premier League which is the most competitive league in Europe, so it seems difficult for Arne Slot to be able to bring Liverpool better than Klopp has doing so far, let alone him must to maximize last season squad which has many weaknesses in several sectors, In my opinion, Liverpool attack line is no longer as sharp as before because of their main striker (Salah), who in several seasons has no longer been at his best, as well as their defense line last season quite fragile, so without the addition of new players the slot job will actually be even more difficult next season and looking at all the possibilities, it looks like next season we will see Liverpool get out of the big four zone.
