The rules are clear and we should get registered 3-0 win. But sadly I can see Napoli getting away with this stunt. Against any other team, Napoli would be punished. But considering Juventus is involved, it will prolly get postponed, which will put entire season in jeopardy. From now on any team may call the game to get postponed and once the precedent is made, it will be hard to go back.
