Inter were going to win the Scudetto had they had Zlatan or not. They would have replaced Zlatan with someone else like Eto'o for instance

if Ibra didn't accept the Inter move back then.
Milan sold Shevchenko right before Calciopoli. They intended to replace him with Zlatan and failed because Secco accepted Inter's offer which was just a million higher than Milan's.
I know you usually underestimate Zlatan's importance in winning scudetti, but with that man replacing Shvchenko Milan were gonna be unstoppable, at least in serie A.
Inter were definitely not gonna buy Eto'o back in 2006. His price would have been 50m eur or something. And they weren't gonna buy a top class attacker. They simply got lucky with Zlatan. Even when they bought Zlatan for 25m eur from us, many Juventini laughed at Inter for buying a flop.
If it wasn't for Zlatan they were probably gonna buy another hyped future flop, like the ones they were buying for years.
If they didn't buy Zlatan, they were never gonna get the 49m eur+Eto'o and create that CL winning team with the Zlatan money.
So yes, I am convinced that what brought so much success to Inter wasn't Juve's relegation per se as much as the product of Juve's relegation i.e Juve selling Zlatan to Inter.
I didn't say Milan aren't involved but it depends how you define being involved, Media? Yes they were of course. But working together with Moratti like that guy is claiming? Hilarious.
Milan knew about Calciopoli being prepared. They simply couldn't have been kept in the dark. It was impossible the prime minister not to know what Moratti is planning to do. There was a reason why Galliani didn't make the phone calls and Meani made them all.
And the Milan-Juve antagonism was really high in 2004/05 and 2005/06. We were the two clubs fighting for the scudetto back then. Exactly in those two seasons the media, most of all Berlusca's, prepared the public for Juve's relegation. Like never before, every single semi-mistake in Juve's favor was getting hours and hours of TV time and the Italian public was hand directed into thinking that Juve are cheating.
Calciopoli was a process being prepared for a long time. The main people in Inter and Milan knew that it was going to happen.
