I'm not questioning Gazzetta's links with Inter at all, gsol.
I was only talking from personal experience with Gazzetta. I read them more or less regularly and i know that Milan are their main interest. Many of their articles (actually most of the articles) seem like they're written by Milan fans. They are always the first Italian papper that has exclusive info about anything happening in Milan, about potential transfers in and out of the team and they always seem to "forget" to write about the bad things happening to Milan while they never forget to write, or even to give 2 or 3 pages, about the bad things happening to any other team, including Inter.
They are pro-Milan the same way Tuttosport is pro-Juve
In the past it was disguisting how anti-Juve they were. Now things are different and they're not giving us the hard time anyomore.
As for Inter....they threat Inter like any other team apart from Juve and Milan. They are more or less objective when they write about Inter, Roma, Fiorentina, Lazio or Rimini.
Even more, lately they seem to attack Inter a lot for the favours they've been getting from the refs and they use video evidence to prove how Inter are being favoured by the refs.
That's why i found it strange why people have been saying that Gazzetta are "Inter's newspaper"
