If Enzo Maresca doesn’t perform well next season, then what happens to other Chelsea coaches will definitely happen to him. Chelsea doesn’t have patience with their coaches, if a coach doesn’t perform well, he will be sacked immediately. They want a club that will change Chelsea's performance instantly, not  one that will improve the club's performance gradually. So let’s see how Enzo Maresca will perform. I am sure he will do everything possible to improve Chelsea’s performance because he won’t want what happened to other Chelsea coaches to happen to him also.
