Well, they had an opportunity to make this upcoming season much better but they decided to let it slide by kicking Mauricio Pochettino out, that man took them to the Europa League spot after several errors by previous coaches and if not that Manchester United defeated City to win the FA Cup, Chelsea would've played in Europa League instead of Conference League, but then how did the board pay him back, by cutting ties with him when his bond with players on an off the team became strong. Enzo Maresca might encounter lots of difficulties and things might be worst than other coaches, not leaving behind the fact that he could have a serious confusion in selecting his best XI due to bulky squad depth. As for changing Maresca, it won't come like a surprise given that Todd Boehly lack patience and won't hesitate to look for another option if Maresca doesn't miss his expectations.
I also think that Pochettino's dismissal was a mistake, especially since it was inappropriate on Boehly's part, because he had previously said that their cooperation with Pochettino would be long-term and that he should concentrate on working in the team. And if he had stayed in the team, I would have expected better results from Chelsea than now, when Maresca has joined the team, and there are many changes in the team again. Perhaps it's not even that Boehly has too little patience, but that he makes wrong decisions regarding coaches. By the way, I think the time when Pochettino was a coach was the most adequate period regarding transfers.
Some time ago I read one of the users of this forum said that Pochettino and Todd Boehly were both having problems, whether they were not compact in working together or other problems, therefore the management ended the cooperation between them because it was not good if it continued when the two were at odds, but I think this is just the club's excuse because Todd Boehly usually always makes the decision to fire a coach if it does not match his expectations.
I just hope that after the incident of firing Pochettino there will be no more drama regarding the next Chelsea coach and Todd Boehly will not be reckless in making decisions, at least he should give the new coach time to adapt to his club.
