"Napoli's football makes me enthusiastic, as does the city," he told Corriere dello Sport. "It's a team that can only hurt itself because such enthusiasm can make you do great things, but it can also destroy you.
"We need to be clearer. Napoli are a great club with great players. There are all the conditions to do well there. The fans are fantastic, but this enthusiasm can be bad as well. Napoli's worst enemy can be Napoli itself.
"I agree with Balotelli when he says never say never. He has remained enthusiastic about Napoli. It has been important for him to leave Italy."
