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.
Exactly, to be honest even if Manchester city is in the relegation zone Pep Guardiola will still remain the coach of the club and will still have so much backing from the club and fans. Some people actually think it's an easy fit to win the EPL 4 times in a row. Pep has been too dominating that he almost made EPL seems more like a farmers leagues, Whereas, in reality it is among the most competitive league. I don't even want to talk about how he has made Manchester City among the top club in the world, challenging clubs dominating for years.
Mikel Arteta will be the one with more pressure about losing his job especially next season, if his team are unable to grasp their hands on any trophy this season. He has been given enough time and resources, but till now, no significant trophy. Although I don't like speaking gunners because the face are just too happy seeing their team coming out among top 3 on the league table, after many years of a decline state.
