In the last two seasons, Chelsea management's patience has been very thin, so there has always been a change of coach at the end of the season, ignoring their own players. In fact, most teams only consider purchasing players more than changing coaches each season, which generally does not result in significant changes in the team's appearance. And on the one hand, I also agree more with your opinion on this one, where the Chelsea team must have sufficient patience in enjoying the process of improving the team's performance in the new season.
With the way Chelsea management is buying young players, I don't think they will be patient with the new manager if he fails to get the result they want for the club. If Enzo Maresca fails to improve the team next season, I believe they will fire him, just like they did with Pochettino, Chelsea management changed the entire squad, selling the old players and bringing fresh blood with the hopes of easily winning the league, but when Pochettino failed to give them the results at the end of the season, they decided to fire him. The Chelsea owner needs to learn from other clubs, such as Manchester City. They didn't win a trophy the first year they hired Guardiola, but they should look at Manchester City, who won the treble the previous two seasons and the Premier League title four times in a row.
Enzo Maresca will not be successful in the first season because this is the Premier League, it is difficult to accept any club and become successful in the first season because there are other competitors in the league, Arsenal and Manchester City are playing at the top, making it difficult to compete with them. If Pochettino is still the manager, I believe he can compete with them since he has already adapted to the club.
