I think I know what happened to Dzeko deal.
Man. City Sheikh's knows Cannavaro is very close to Ale and since Fabio lives in Dubai it was easy for the rich Sheikh to meet up with Fabio and ask him to speak with Del Piero to stop Agnelli and Marotta from signing Dzeko and give Man. City free road to sign the Bosnian player. Eventually, Cannavaro managed to convince his close friend Juve's captain and Del Piero prevented both Marotta and Agnelli from signing the Wolfsburg player.
Incredible what Ale is capable of.
