Man City didn't even play Euro league last season and they signed players like Tevez, Adebayor, Barry to name a few.
If a team like City can attract players like that with cash, then why would a team like Juve be unable to attract a player like Tevez, we have Euro league, we have a history in world football and if the rumours about the 80mil is true, we have some cash to spent.
I don't think a player like Dzeko is an unrealistic target.
