GdS, CdS, and lately TS too, are all linked to Inter. They're owned by this huge publishing company called RCS Media Group, a company who has financial and historical ties with Inter. Don't get distracted by the headlines, though. Of course they're covering many of Juventus' news on their headlines. It's simple economics.
Il Corriere dello Sport itself is run by a fag named Bruno Bartolozzi who also serves as Inter’s team manager (the same position Pessotto has with Juventus in the past).
So it's no coincidence that they (the newspapers, not sure about the clubs) tried to exploits their influence on the transfermarket for political-strategic reasons.
Only in Italy.
