It would be foolish to expect a better performance from Chelsea. Maybe the team's performance will stabilize a bit. But I don't think Chelsea deserve to be in the top four of the points table at the moment. This club has a lot of internal problems. The management of the club is not experienced and this is their first weakness.
However, this season too, Chelsea will form a squad with a new coach. Looking forward to seeing if Enzo Maresca will make Chelsea stronger again. But the Chelsea team is in a very bad position right now. Rapid improvement is not possible for this team. But if Maresca has long term plan then maybe Chelsea's overall situation will change slowly and we will see stable performance from Chelsea.
The problem with the Chelsea club even when the coach has a long term plan for the team to be victorious in the future, you’ll just see the President sacking the coach after just one season flop and that’s not how to built a strong team. You need to have a transitional structure before you can achieve that and if you don’t follow it duly, you’ll cause the team not to rise amongst others in many years to come.
Chelsea’s poor performance have been on for more than two seasons now since the sack of Thomas Tuchel, all the coaches that came after him really did their best but Pochettino was the best man for the job but was sacked just after a season. Now they’re back to square one and need to start building the team again. I hope the same fate of Pochttino don’t happen to Enzo Maresca by end of the season.
I wouldn't say all coaches after Tuchel at Chelsea did what they could. For example Potter tried to please the players, the fans and the management, eventually he got a reputation as a soft coach who is not listened to by the players and as a result led Chelsea into a deep crisis from which Pochettino brought Chelsea out, but apparently Pochettino was tough enough when it came to transfers and that's why he was sacked. Maresca so far seems to be a tough coach who speaks his mind and doesn't hide anything from anyone.
Recently Maresca honestly said that he doesn't see Sterling and Chilwell as core players and Sterling is likely to be sold quite easily, especially if they set a not very high price for him at 25-30 million, but Chilwell I think will still be on Chelsea's books until he is loaned out.
