There is an Agenda.... making money.
which is why there's many negative stories about City as this engages all the Rags/Dippers/Gunners fans into clickbaiting.
Most people aren't aware of this as they just think: hey, news story here, it keeps me entertained, failing to note the reasoning behind a company employing somebody to write the article and publish it on webservers which cost money to operate.
This then further increases the hatred towards City from these club's fans and they start reading this kind of story even more, clicking more news stories about City.
The same applies to let's say Daily Mail and their "immigration" keyword, which targets a certain mindset of people.
Thus making them money.
The actual guy who operates Daily Mails server could be the biggest City fan in the world, or a left wing socialist, but he's paid a decent salary to publish stories about how much City are "moneybag" cunts, or how UKIP are here to save the white race.
