It would be impossible from a legal point of view. Let's say the FIGC agrees and gives Juventus the scudetti back. The FIGC were also responsible for Juve's relegation back in 2006. If they now say Juventus did not do anything wrong, they have no basis to justify that forced relegation anymore. No one can deny that the relegation cost us a lot of money. So if the FIGC gives us our scudetti back and we sue them for compensation, they'd have to give it to us.
