I know clubs like Barcelona and Bayern had exclusive deals with Konami, but they still were in FIFA with their name and real kits. They just didn't have the stadium, manager, and maybe some authentic chants in the game, if I'm correct. But everything else was there.
How the hell can Serie A not pull off a similar deal? If you're a big brand like Juventus, AC Milan, or Inter, there is no reason you shouldn't be in both games.
