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.
Chelsea actually have players that are capable of bringing result to that club but unfortunately it’s surprising to see how some of these players performed excellently in their previous clubs but their performance decline after joining Chelsea. I don’t know if it’s the couch fault or the entire system about the club. There is a saying that Rome was not built in one day. It will definitely take Chelsea some time to rebuild the team to be on their former track but do they have that time to exercise patience. Other clubs can tolerate a manager even in their trying time but Chelsea doesn’t belong to that category despite it is not bringing them result.
