During Abramovic era the manager keep existing around more than one until two season without sacked them such as did by Todd Boehly era because some manager leaving their position without one season over. Chelsea faced difficulty return back to be big four team of premier league since acquisition by Todd Boehly and never yet participants in Champion League or Europe League competition. Chelsea under Todd Boehly era made more interventions in recruiting players, even Pochettino had to leave his position after not being given the freedom to recruit new players.
Build up one team with full youth player need time for development and I think Chelsea owner more patience waiting for giving opportunity more longer time to manager find right tactician. In this season Chelsea will perform in UEFA Conference League and its opportunity after absent last two season with European competition.
Todd Boehly doesn't seem to understand how to build a team and Chelsea's management made a lot of mistakes so they are down like they are now, they don't want a process as if everything can be bought with money, that's a big mistake and if that can't be changed then forever Chelsea will not develop.
Everything takes a process and time to build a team, like what Manchester City did several seasons ago and Chelsea management should be able to do the same thing.
Now Chelsea has a new coach and I am pessimistic that Chelsea can recover in the near future.
In fact, Todd Boehly is not at fault regarding Chelsea's current failure, but for me this mistake occurred with Chelsea management who did not manage their finances well so they bought players who perhaps did not have good talent but instead were determined to buy these players while Todd Boehly just left all of this to management.
Meanwhile, the management mistake was even worse when he fired Pochettino who had worked hard to rebuild Chelsea's strongest performance and this is a big mistake that Chelsea has often experienced since last season, which is always trying to change the coach when they are trying to improve Chelsea's future and I agree with If Chelsea really wants to get good results, you should try to look at Manchester City, which has successfully won various titles just by retaining its old coach.
