I think Liverpool have a solid squad and they are still worthy title contenders. They have a new manager because Klopp wants to take a break from football. Arne Slot will have no problem with the team he has now. But as you said Slot has to be careful and has to be able to rotate the squad well to minimize the risk of injuries. It will be a problem in his first season if many players get injured. But I think it is difficult to avoid injuries because no one knows their unlucky day.
Because no one knows when each player can get injured, that is what will make the coach think about being able to rotate players very well before the players get injured. I also see Liverpool's squad which is still quite solid at this time so that the Liverpool team will still be considered by its rivals in the Premier League because there are still some of its mainstay players who have not moved to other teams so that Liverpool must still be considered a strong team in the Premier League this season.
