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.
Recruiting quality young players is aimed at long-term investment, that is quite good, but the coach must also be smart in being able to combine with senior players in the squad so that the team's performance remains stable.
Feyenoord was the last team he managed before he was appointed to replace Jurgen Klopp who resigned. With Feyenoord, Arne Slot was able to give a good performance in the Eradivisie, he even managed to win the title for Feyenoord. However, the clear difference here is that he will face a more competitive level of competition compared to the league he previously participated in.
I won't rush to say that he will fail or he will succeed with Liverpool, because we have to first see what he can show with Liverpool in his first season. It is normal for there to be people who doubt Arne Slot and there are people who believe in Arne Slot. But we'll see what will happen when the season gets underway. Because after all, now he has quite a long time to see the extent of the strength he currently has at Liverpool. Several upcoming players will also help him in his new team.
