From Chelsea we can learn that in the end no matter how much money we have but when a club does not have good management and good club management then everything will not be able to become anything because it is just like a bad investment today.
Chelsea have finances that are more than enough where when other clubs' problems always implicate money as happened for several EPL clubs such as Leicester or several other small clubs but that is not a problem for Chelsea because Todd has more than enough resources to advance a club but in the end only money alone cannot guarantee that a club can rise because apart from money as a support, of course there must be good management to manage a club to run well and that is what Todd's Chelsea era does not have now which makes their money seem wasted without producing anything in the last 2 seasons.
While we are getting near to the end of the season, again we see some news about Chelsea and the players they can buy during the end of this season. As you said Chelsea is not a team with a good management system and doesn't matter even if they change their coach or buy some more players. Chelsea hired Pochettino and we know Pochettino is a coach with knowledge but he still couldn't have good performance in Chelsea.
Now they want to hire some more players and even Victor Osimhen is linked to Cheslea for the next season but I don't think if they will be able to hire Osimhen if he accepts the offer from Cheslea with the current situation of Cheslea.
For now, changing coaches or reshuffling players for Chelsea is actually an action that is not too necessary because after all, it makes them worse because they have to adapt again and again because they do not believe in the process they have.
What must be done now is to give time and space to the players they have because after all at this time what Chelsea must need is chemistry and they cannot get that if they continue to dismantle every season considering things like this will actually affect performance and teamwork.
It is not wrong if in the end they add one or 2 players but for the whole as they always do every season I think it will actually make them hassle and in the end the money spent is wasted.
At this time Todd must realize that the overhaul scheme and wanting instant results every season with new players sometimes does not match expectations, therefore the new way by waiting is not wrong if they really want to try.
