Its just clearly unfair. First of all it's a nationalistic sentiment that has few relevance to a private owned sports team, why sould city shareholders care beyond perhaps the extra income they could receive from having poppular English footballers? Most of those shareholders are foreigners, its similar to any other foreign owned private company on youre soil.
Second the fair argument is there that its as much as a bpl issue as it might be a city one. Or in fact one could even whine that real madrid is having too few brits, are they anti brit?
Lets get real, whoever decided to put out that article was most probably quite concious of these fair considerations but chose to print it anyhow, which makes me think that its impetous was more like "what kind of dirt can we throw at city" rather than any real concern for brittisch youth.
