Juventus coach Antonio Conte was left disappointed after missing out on the Double.
"I do not enjoy losing, especially in a Final," the Coach told Rai Sport.
"We ought to be angry. This match has to make us understand that we must always go at 2,000km/h.
"Tonight Napoli had something more than us. This is a young group and we must always keep in mind what we needed to do in order to win.
"We also had a few players like Arturo Vidal and Stephan Lichtsteiner who were not 100 per cent fit. The regrets are there, because we didn't want to lose."
