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.
Indeed, with a change of coach, like it or not, they have to start adapting to the new coach, including the players that Todd recently brought in. New players enter the team, they must adapt so that cohesiveness can be realized. This condition is not a problem for the Blues because Pochettino has time to make improvements to prepare for next season. Chelsea can't get anything while the Premier League is running, I see one of the factors is that Todd bought too many players in the middle of the ongoing season, without him knowing that they needed time to adapt to the team. Todd overspends and gets nothing.
