Really bad article though, isn't it?
Sentence 23, way down the text: "There does seem to be something about Ramsey that brings out the crazy in people."
Yes, it is his football.
The author then proceeds to theorize the fans' dislike of the Welsh Wizard might originate in the Wilshere-faction of the fanbase, who allegedly see Ramsey as a rival.
Close to the end of the article, the author comes to a conclusion I wholeheartedly agree with:
"Ultimately, these are just theories I have plucked from thin air."
