Even if there are no key players leaving Liverpool, it doesn't guarantee they can maintain their game level and are still competitive as the previous season. The new coach may change their tactics or strategy. Also, the coach may change the formation and change the player in the main lineup. This potentially changes the game style of Liverpool for the next season. We don't know the change can bring a positive result or even a negative result on the team performance.
So far, I don't hear a big plan from Arne Slot to sign certain players. In the last season, Liverpool has a problem in the striker position. Darwin Nunez could play as expected, Liverpool has no strong striker. I think Arne Slot needs a stronger striker, Liverpool can try luck by negotiating with Napoli for signing Osimhen. Or targeting to sign local strikers such as Alexander Isak and Ollie Watkins.
New coach have new tactician and can't guarantee with regular players get more minutes playing under Jurgen Klopp era has the same chance for next season with Arne Slot tactician. I think all players need time for adapting well with new tactician of Arne Slot exactly its first his experience with premier league know most difficult competition and not sure yet for the first season he will be success. Liverpool still haven't official announcement yet with new recruitment although they have many position need back up with new players exactly as central forward regarding inconsistency performance of Darwin Nunez.
The rumor of Mohamad Salah linked with Saudi Arabia club have reduce and seems keep staying with Liverpool until his contract over, not guarantee with Salah as key players under Jurgen Klopp era will get regular position under new tactician Arne Slot behind he has favorite players from Dutch Cody Gakpo had impressive performance in Euro 2024 with his national teams. Still difficult for speculating with regular or substitutes players of Liverpool next season.
