Napoli are threatening to play their youth team in the second leg of their Coppa Italia semi-final against Juventus in protest at first-leg refereeing decisions.
The Naples club's director Cristian Giuntoli described the performance of the referee Paolo Valeri as "shameful and damaging to all Italian football".
Valeri awarded the hosts a penalty at the start of the second half after apparent contact between Dybala and defender Kalidou Koulibaly.
He awarded Juventus another penalty when they were leading 2-1 after former Liverpool goalkeeper Pepe Reina brought down ex-Chelsea winger Juan Cuadrado.
Napoli feel television replays proved Reina touched the ball before the Colombia winger was upended.
They also believe they should have been awarded a penalty seconds earlier when Raul Albiol went down in the opposition's penalty area.
Napoli's mayor Luigi De Magistris then became involved in the controversy, releasing a statement which said: "Yesterday in Turin we suffered once again from an injustice, a game that was full of, and influenced by, repeated refereeing mistakes. It was a disgrace on top of disgrace."
The second leg in Naples is live on Sky Sports 2, on Wednesday, April 5 at 7.45pm.
