I think inheriting a good squad can be such a big present from your predecessor. When you think about the coaches that became the successors of prime Guardiola Barcelona, it was like Christmas for them. They still had to manage the team and you could see that Koeman for example couldn't do it as well, but it's a huge advantage.
Slot did much better than expected, but he benefitted from two main conditions. One is that he did indeed inherit an outstanding squad from Klopp and that is a big deal. The second big advantage he had last season was that there was no competition. Remember the seasons when Liverpool and Man City were head to head until the last day and it was only a point and goal difference. The pressure never stopped and the tiniest of mistakes could cost them the title. It wasn't like that last season. In that regard last season was more of a relaxing walk than a marathon. Liverpool was the best team by far in the first 30 matches, but the other teams were losing points all the time. After 13 weeks into the season, Liverpool was leading by 9 points and Arsenal and Chelsea followed them with a rate of merely above 50% winning their games.
That is true, he definitely did inherited a great team, but majority of people are saying while it is true that the team was good, it is also important that Slot did a great job at it as well. We have seen him do a great job with a great squad. The trick is to make sure that you partner a good team with a good manager and Liverpool did just that.
The only difference is now shown during the summer, team spent a ton of money, I do not remember the last time any team spent 300+ million in a summer, so Slot now has a much bigger responsibility compared to last season. It is not enough to win Premier league this year, he should do that, but that's not enough, he needs to win one more, preferably UCL, but even if he fails at that, then he should get EFL and FA to round it up.
