Sarri was sacked by Napoli president Aurelio de Laurentiis as the pair fell out in the final days.
“I love the people there and I will always love them. If we parted on bad terms with the club and the President then I think mistakes were made on both sides.
“Maybe the President misinterpreted some silences of mine, these were the uncertainties of someone who was torn, thinking it might be time to go.
“But I was heartbroken, and I hope in the coming years all of this can be overcome."
