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.
If Todd Boehly gives every coach who comes to the Chelsea club a long time, then this club can actually develop better. And likewise, if Enzo Maresca is given a few seasons, it is very likely that Enzo Maresca will also be able to make Chelsea better with the existing squad. And now Enzo Maresca has just started at Chelsea so we shouldn't have too high hopes in his first season. Because building a squad to be the best definitely takes time. And now we are also at the start of the season so we can't make an overall assessment yet. And yes, I also feel that Chelsea will most likely find it difficult to compete for the top 4 rankings. I think just being in the top 10 this season will be good enough for this team with its new coach.
You are talking about the top 4 ranks and I think you are expecting to see Chelsea in the top side of the table in this season while other teams like Manchester City, Arsenal, Aston Villa, and Manchester United but better situations than this team and compared to these teams, they can have much better performance than Chelsea.
I think since they have Todd in Chelsea managing everything, they can't get improved at all.
