One thing about the Citizens is that no matter how they struggle to get back to winning ways you can never see the coach or any of the players coming on air to say this is why they're having issues or because of too much fixtures that's why, no you can't hear such complain from them, they'll try as much as they can to not let people see much of their frustration, Pep has given these guys that idea of always maintaining their cool while on air.
Before either Chelsea or Arsenal can take over from City completely in dominating the league I think that will be when Pep Guardiola is no longer with the Citizens, even when he's no longer their other teams will step up too to compete for the title, is not only City who can make the EPL hard for other teams, every season we see how some of the smaller clubs get transformed to be at their best so is going to be a long ride for the big 6 to always be at the top.
