Because City is an obstacle for the yanks to seize the Premier League. Their proxy war is been ongoing for a while and they can boast Chelsea as their first beach head, the red franchises their warships.
The yanks want an english football (sawccer) clubs ownership monopoly of their own, modelled on their riot geared hand egg.
Some of you lot have talked about muricanisation of language, that's nought compared to what's coming. Bliar and Bush, Bozo and Biden, you've got the drift. It won't end unless England obtains independence from their yank masters.
The media are sad hirelings from their yank paymasters, toeing the party line of throwing all the propaganda slander against City; and the Brits, gullible and dimwitted by nature, fall easily for the yank fake news campaign.
The media know how to do it, as they are very applied pupils of one Herr Goebbels:
Lie continuously and some will stick.
