The current problems Chelsea are suffering from are too difficult to solve. Blaming Pochettino for his decision to reshuffle earlier will also not have any impact because his performance has not changed. Poche did what he thought was good and I think he also tried to do something for Chelsea to improve but in the end his decision was still wrong.
The change from Potter to Lampard some time ago I actually said that Lampard would only be a sacrifice for Chelsea and now for Poche is also the same in the end he will be a sacrifice for Chelsea's poor performance.
The uncertainty of who is to blame will make the coach affected in any case so that what Poche did before will still be considered a mistake.
Responding to Chelsea situation, I think the same as Man United, it is true that the steps taken by Pochettino are the best for him. However, the fans' orientation remains on winning, as does the club owner. The absence of several key players cannot be an absolute reason to scapegoat a decline in performance. What happened was a form of club policy that did not take into account the players they recruited, who were young, had little experience and were expensive.
When adding players cannot be done, changing coaches may not necessarily improve performance. Automatically, The Blues have to survive and find the best way out for now, by not competing in the UCL, Pochettino should be able to do it more quickly.
