De Laurentiis told Gianluca Di Marzio of Sky Sport Italia: "Walter Mazzarri is a friend of the De Laurentiis family and of Napoli. It is a painful farewell because he was extremely available in a moment of difficulty, but we must also consider that something more must be given to the Napoli fans. Now let's try with Calzona who has worked with [Maurizio] Sarri and [Luciano] Spalletti and knows 80% of the players. Let's give him help without putting obstacles in his way because we know that it will be difficult to prepare for a match against Barcelona who are always Barcelona. Tomorrow morning at 8:30am, Calzona will be here with his staff, then we will go to Castel Volturno where I will introduce him to the boys. [Marek] Hamsik was very intrigued to work for the team he loves and which has given him so much satisfaction."
