Indeed, since Chelsea changed owners, their performance has become worse and unstable, as if they have lost their playing philosophy. In the Boehly era, coaches changed, but their performance still did not improve, they even bought young players with potential, but the results were still unsatisfactory, which led to the dismissal of coach Pochettino. I also think the same as you, Chelsea's current instability is caused by Boehly not wanting to be patient with one coach even though we know that building team strength takes time.

Now Chelsea has a new coach, Enzo Maresca. Even though Chelsea's decision to fire Pochettino was too hasty, I believe Enzo Maresca is the right choice. It's true that he doesn't have much experience, but he is believed to be able to bring Chelsea back to competing in the EPL league. The reason is that Enzo will be the coach that Chelsea dreams of after successfully bringing Leicester City promotion to the EPL, and make no mistake, currently there is a trend of recruiting coaches with minimal experience to train big teams, maybe they will take an example like Xabi Alanso. at Leverkusen who has little experience but could make a difference. Leverksuen is also like that.
