Since the beginning, Liverpool management has been looking for a replacement for Klopp whose playing style is as similar as possible to Klopp's game so that the transition of changing coaches is not too difficult for the game and so far Arne Slot has succeeded in coaching Liverpool.
What you said is true. It is still too early to say that Liverpool will be consistent until the end of the season considering the very tight match schedule this season. Fatigue and injury problems could affect Liverpool's performance. So to overcome this, Liverpool still needs 2-3 players in the midfield and back for squad depth. the performance of players like Ryan Gravenberch so far has certainly been a surprise and on the other hand it is something to be afraid of if later he is injured/accumulates cards, because there is no equivalent cover in the existing squad. So Arne Slot has to buy a few more players to back up the core players.
Liverpool is still good, no doubt, and even after changing their coach, they still keep their consistency. There is nothing different with the way they perform with the former coach; furthermore, let's see if they will be able to keep their consistency till the end of the season; they just start the season with good performances, so I’m expecting Liverpool to make things possible for themselves. I can’t choose Liverpool because my favourite club is there too, and I really want them to win the Champions this season.
Lastly, we should not give Liverpool higher chances of winning the title. The season just started; we have not gone anywhere. We should calm down for them to see what they will do.
