I wouldn't comment on such a thing without getting a decent-cross sector to look at. Every club will have deluded fans, etc.
What I will say is that though there's a narrative that is perpetuated in the media for a wide range of subjects to make them more digestible for the lazy who do not want to scratch below the surface to see the facts. Some of which are the following within football alone.
* Stoke are a long ball team
* All Man Utd fans are from outside of Manchester
And of course the 52,000 every week, Newcastle fans are deluded idiots, etc.
It's just so everything can have it's own little label to fit in within an easily absorbed form of information.
Of course both Newcastle players, incoming managers and fans don't help themselves by perpetuating it. Whether that it spin that has been put in front of players/managers by the PR people or not it's ill advised.
