To be honest, I'm not sure about that.
Arne Slot is not a coach who has experience handling big teams, especially those who play in very competitive competitions like the Premier League.
Let's look at some examples of previous Premier League teams when a coach who has been in charge of the team has left for a long time, of course there will be a drastic decline that occurs and it will take time for other coaches to go through the process of re-developing the team, that is also what will happen to Arne Slot's season. ahead I think.
Liverpool is a tough team and is also big enough in the Premier League that in general every coach must have better abilities to train them. Because it would be very strange if everyone saw that Liverpool was in a bad ranking just because the old coach changed to a new coach. And next season looks like it will be a much fiercer season in the Premier League, especially in terms of competing for the Premier League title so Liverpool needs to be on a good track even though the team will be handled by a new coach.
