You should know football comes with a lot of banter, fans will always say things out of proportion, because you can imagine for the fact that Manchester city is facing these little turbulence and some person's are already calling for pep Guardiola's sack, forgetting that he is the premier League defending champion, a position he has held for good four seasons back to back. Given the kind of coach Guardiola is, he just needs time to come up with a better tactics because the one he is currently using has been understudied by lots of teams, which is why they can easily predict the playing pattern of Manchester city and how to tackle them.
The real cityzens will not ask to sack Pep because they know Pep is the best manager for them. People who ask to sack Pep is actually come from The Gunners, it's because they want Pep to become their manager, Mikel Arteta contribute nothing for them, they can't lift prestigious trophies.
The poor results achieved in the last few matches will not change the view or lose confidence in Guardiola because so far he has given everything for Man City. The fans and management will not ask him to leave even though the team's current condition is not good, in their eyes Pep is still the best coach and his position is very difficult to replace. I have no information about this, if there are fans asking Pep to leave Man City, maybe they are Arsenal fans in disguise to worsen the current situation.
