Chelsea appointed Enzo Maresca as the new coach and Liverpool along with Arne Slot who replaced Klopp who chose to take a break from football. Having a new coach is something good to improve the club's performance but for the first season I don't think we can say that Chelsea and Liverpool are title contenders.
Chelsea fired Pochettino who was deemed not to be providing good results for the club and Enzo Maresca had to create tactics that could be implemented optimally by Chelsea players. Arne Slot came in to replace Klopp and Liverpool have been title contenders for the last few seasons but new coaches usually need time to adapt. But I think Liverpool is more worthy of being called a title contender than Chelsea with the squad they currently have.
Appointing a new coach is not the right step because the percentage of the new coach who can continue or make the team much better is not that big, especially for the Liverpool team which has been coached by Klopp for a long time with all the achievements that Klopp has given to the team, but they have no other choice. because Klopp has decided to retire.
It will be difficult for Liverpool to return to their best performance.
Meanwhile, Chelsea appointing Enzo Maresca is actually a good decision, but Chelsea management has shown a bad attitude in recent times, they often want to change coaches without waiting for the process to take place, if they continue to do that then it is very likely that Chelsea will not be successful with any coach.
So it is clear that teams with new coaches need a process and the percentage for them to immediately perform well and be able to compete for the title is very small.
