Following an impressive season in which Napoli finished third in Serie A, president Aurelio De Laurentiis is confident the club can challenge for the Scudetto next term.
Napoli looked to be title contenders at one point during the campaign but fell off the pace at the turn of the year.
However, a strong 10-match unbeaten run to close out the campaign saw them move back towards the top of the standings and proved they could be a force to be reckoned with next season – provided they can keep hold of their top stars.
Speaking at the club's end of season dinner, De Laurentiis praised everyone involved in their 2016/17 campaign and spoke of the future with much optimism.
"I thank all of you, for you have given us and our fantastic fans a truly extraordinary campaign. You have proved that any record, you are capable of breaking," he said.
"I am convinced that by following this path, we can fight for the most important target next season.
"Sarri, I chose you, I wanted you and I have always been convinced that you were a great Coach who gets straight to the point. Your strength is your great humility.
"I am in your hands and from the depths of my heart, I know that I made the right choice."
