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.
Apart from very little patience, Chelsea management made a big mistake when appointing Pochettino as Tuchel replacement, they should have seen the situation that occurred at that time from a positive angle. Pochettino is not an accomplished coach, he was often fired due to his inability to handle the club according to management's expectations. When clubs often change coaches, the players have to adapt again to the tactics and strategies used by the new coach. The club will also be greatly disadvantaged by having to pay compensation from the remainder of the coach's contract.
Enzo Maresca who has just received the trust of Chelsea management, must be able to make Chelsea appear consistent. Management has high hopes for him because he is amazed by the achievements he has just made with Leicester City. His first season in charge of Chelsea may not go as desired because the level of competition in the EPL is very competitive. Management must be patient with Enzo's work because the success or failure of a coach is seen when he enters his second season managing the club.
