Napoli president Aurelio De Laurentiis says he remains enthusiastic about the club.
Napoli meet Juventus on Sunday needing a win to keep the title race alive.
“We've spent so much money over the last 15 years, but until I get tired, I will continue taking this club where it deserves to be. We are protagonists and want to remain there, as the future belongs to Napoli," ADL told the Corriere dello Sport.
“Sooner or later, we will win the Scudetto. It is still an open wound from last season and I think it'll stay that way for a while. Many people suspect something is going on with the way the league is run, not just me. It's also a fact that this is a common problem in many other tournaments.
“I want to make one thing clear, though: VAR was introduced to avoid refereeing errors. If it is not used conscientiously, then it's inevitable people will think badly. And I had many doubts last season."
