because I saw several Chelsea players who seemed to be getting bored or lazy to use their strong performance in every game. so it's true that it's a waste to change coaches a few times but Chelsea's players don't have the consistency to have the desire to win any trophies.
The points difference of Chelsea with the other top clubs are far, that's why they're not trying harder because they're wouldn't get anything. Lack of chemistry with the sudden many players change were ruin Chelsea performance. There's always a difference when you're playing with your best friend and new player, you will feel awkward and not really trust with each other. It's really hard for midfielder to trust which striker when there's no striker better to score a goal.
It was not easy for old Chelsea players to go through the season with a new atmosphere and this was compounded by the dismissal of Tuchel when the league had started. The sudden change of coach certainly changes the psychology of the players so that it has a big effect on the team as a whole. Then, with a difficult situation like that, it also greatly influences new players to adapt so that the new players don't seem to have a mentor to be able to bring out all their abilities. But for next season under Pochettino's control, of course Chelsea will start a new page, he will have enough time to make plans with the players and of course Pochettino will immediately campaign for a revival for The Blues.
Firing Tuchel was not a wise decision by Chelsea management. Tuchek is a good enough coach. Given enough time, he might have been able to stabilize the Chelsea team. But the Chelsea management was looking for a new coach. And the new coach could not have any impact on the performance of the team. Instead, Chelsea's performance has gotten worse. Coach Poch is good enough. But he should be given adequate opportunity and time. At the same time, he should be given the opportunity to form the squad with players according to his choice. If the Chelsea management does not give Poch enough freedom, Chelsea's performance will not improve next season.
