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.
Chelsea was to quick to be sacking Mauricio Pochettino everyone deserves a chance to improve I can count how many coaches Chelsea have sacked within two seasons and if they continue like this people won't really have enough time for their strategy to actually work, but all Chelsea care about is instant result and for them to get exactly what they desire they will need to give their coaches more time to be able to establish what ever plan they have an not rush and expect to get results. Winning Europa was not enough for them. If not they would have even appreciated him at least winning a title for them but they want Chelsea to be equal with Manchester City and it won't be possible. They can not be on the same level with Manchester City. And even Manchester United winning the fa cup was all luck to me. Look at what happened to Manchester United during the preseason game with Liverpool they did not even stand a chance against them that is Liverpool for you. Enzo Maresca Will also try is best and and if they don't get results am sure Chelsea will fire him also but this season am sure nothing will come out of Chelsea.
What is happening to Chelsea is just like my country National Team. Well to some ways I wouldn't blame the management of Chelsea because the coach, Mauricio Pochettino was a employed to do well which was to win games and probably win the cup. But whereby the team loss in their his first match and loss the second match and probably loss the third game then, it is better to sack him than keep him to lose continually. All teams be a National Team or Club side games, they all need good coach and good players and that is why if a player didn't do well in the first game and the second game, the coach has to replace him with another player that is good.
The most important aspect of coach is to detect the errors of the players and correct them through coaching and that is why friendly Match is vet important on this aspect on football. Given second chance would have killed the team again. And Chelsea right now needs good players and I don't why they have not taken Victor Osimhen in the team.
