It is not worth giving Pochettino a longer chance because anyway, if for example until the end of this year or it can be said that until halfway through the season Pochettino still cannot restore Chelsea's performance. Then obviously, I believe Pochettino will be fired, because basically Pochettino has a very good time to build Chelsea. But what happened was a complete failure, because when a coach has enough time to prepare before starting the season at that time, the coach should have succeeded in making good preparations for the team. But what happened to Pochettino until now for Chelsea, is clearly a failure and worse than Potter.
There was 6 rounds played in which Chelsea won once, got 2 draws and 3 defeats. They received more goals than what they scored. The only positive match was vs Liverpool where they got a draw in the beginning of the season, we all thought that Chelsea is getting better then negative results followed quickly.
I blame Pochettino also for defeats and points loss but also players and staff. The dysfunction in this club is getting more obvious throughout years no matter how much they spent to fix it.
Just imagine losing today vs Brighton in EFL Cup and leaving it that early..
