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.
Liverpool has a long history of success in the English league and not only that, didn't we know Liverpool before as a team that was quite strong when playing in the Champions League, indeed changing coaches won't change their status as a big team in the English league, but that can't be said It is undeniable that changing coaches often causes a team performance to experience significant changes, whether it increases or decreases, so far Klopp has left a lot of glory at Liverpool and even Xabi Alonso ever to said that it is not easy to continue Klopp legacy of glory at Liverpool at this time and that's why He refused to coach Liverpool before staying at Leverkusen.
Liverpool have officially signed Slot as their coach next season and of course many fans hope that Slot will be the right coach to be able to continue the success that Klopp has built at Liverpool so far, but I think Slot will need a lot of time to improve Liverpool and enable them to return to the competition to win the English League later, but for now perhaps slot will not experience significant difficulties in building Liverpool because he has full support from management.
