I think for them to get back in the Big 6 status, Todd Boehly has to ensure more trust in the manager and the players and let them do their things. If they are given time, things will start going their way more often. The manager that they have right now is great and had a great season with Leicester. He needs to be given enough time, and they will return to who they were 2-3 years back.
Todd Boehly believes that by changing managers every season they will be successful the following season. However, this will be very difficult to achieve. Chelsea is buying young players to compete in the coming season, and the other clubs that won trophies last season are also buying more players to improve their performance. Chelsea will not be able to win a trophy next season because other clubs are also hungry for them. Of course, Chelsea has a new manager who was successful in his former club, I believe that the Championship is a difficult league but not as competitive as the Premier League because it changes every season.
Chelsea management must be patient with the managers since it will have an impact on the player careers and the clubs. They should give Enzo Maresca enough time to avoid losing their players. If any other big club wants to sign them, they will leave because Chelsea did not have the patience that other clubs did.
