Really? Frankly I'd be surprised if anyone in the rest of the country was so aware. Are they getting the impression from TV? Doubt it, it has never been an issue that has come over on the telly. Are they getting it second hand, from the Press? Doubt it, the Press is not interested in anything to do with Everton. I read many newspapers and I truthfully can't recall one article or even a reference to 'the treatment Barkley (supposedly) gets'. That just leaves websites. In other words they are just regurgitating what is being said by Evertonians on our websites. A circular, self-supporting generation of a myth.
PS - do these very aware and knowledgeable associates of yours ever comment on the brilliance of our away support?
