This level of entitlement is problematic. Chelsea were and still are very far off in the league. Chelsea has finished around 15-30 points behind City/Liverpool for the last five seasons with the exception of Liverpool's injury crisis year.
Of course Tuchel is not above scrutiny but this idea that he should be sacked 3 games into his 2nd full season because he has not caught up with a generational Liverpool/City side (accumulating 90+ points) is absurd. Liverpool and City are not envious of the talent at Chelsea apart from James and a fit Kante. They have comfortably better players because they have spent years shaping that squad, signing players who fit the manager's mould.
Liverpool and their process with Klopp is a great example - they finished 8th, 4th and 4th under him but the fans were not calling for his head through this. They picked the market really well and built the team over 2-3 years which became wildly successful.
