Normally Chelsea has that long tradition of actually selling their coaches if they don't do well and example would be roman abramovich impatient on coaches with the club but since Roman abramovich was forced to sell this club, the new owner has been somehow lenient with coaches because I believe if it was abramovich by now porchettino case would have been something that isn't even worth discussing because I believe he would have sacked ever since so porchettino being sacked or resigning by himself isn't really the main issue as the issue currently now is for the new coach to be able to cope with the pressure that fans have left for that space in the club for the position of the Chelsea coach.
It seems like the newest Chelsea owner wants to change the character of Chelsea well, so if the Chelsea owner is soft on many coaches then this shows that Chelsea really hopes to get the right new coach who can bring Chelsea to victory in every match they face. It is a normal task for new coaches to adapt quickly and be able to provide good direction. Because what I know is that the coach will get respect and all instructions will be listened to properly when this coach can adapt well.
The Chelsea owner wants to see the title so any coach who fails to achieve the target will be fired, we know that since Chelsea was taken over, Chelsea has had several coaches and that will happen before Chelsea actually wins the title or at least is in 2nd place in the standings. I understand what the owner expects is normal because he prepared a sufficient budget to bring in players so there is no reason not to achieve the target.
The better for you try to research into Tuchel and Pochettino's background about why they being sacked by todd last year and last months. Todd Boehly let these people go for asking for an allowance in the player transfers which is strictly prohibited by the club. Todd Boehly told them no, and the management was acquiring the new players without consulting the coach.
What Pochettino feels is this. With such desperation and he begged Todd to allow him to manage the players transfer but Todd promptly fired him after he asked that question to the club. Todd was willing to use chelsea as a money printing. Targeting top position combined with young talents will be really helpful for chelsea to sell its young talents with very high price and this is what todd has been aimed from acqiiring chelsea. Claarke is here for money not for trophy. The new coach has consistently run into this issue. Certainly, a lot of Blues supporters think Maresca will leave the team in the midst of the season.
Discussing the realities of big six ambitions without obtaining approval to reconstruct your ideal club is like dreaming and todd how have zero knowledge about football never try to understand it. Pochettino made it under extreme circumstances.
Regarding transfer season. Todd is not the same as Abramovich when it comes to the transfer policy as todd is far stricted than abramovich. Abra gave the coach carte blanche to choose the players. Perhaps there will never be a solution to this fundamental issue owner by chelsea since todd is having mental issue. This fucker keep destroy his own club with his unbelievable decision.
