Chelsea have changed coaches several times but their performances have not improved. Rather, their performance has deteriorated further. Chelsea's performances have been very poor and erratic this season. This clearly shows that the main reason for Chelsea's poor performance is their players. There is probably an internal conflict between the players. This is why they are not playing well. And so changing coaches again and again cannot be a solution. Chelsea needs to change their entire squad. Chelsea's performance is unlikely to improve unless the players change.
the presence of a coach who has good assertiveness is what a team really needs and Chelsea has not been able to find that until now apart from that there are still a number of good friends who have not had a good impact on Chelsea because of the lack of coordination between players, if next season Chelsea's appearance continues like this then what boehly (buying expensive players) did was in vain.
