The Uruguayan striker has been linked with such clubs as Manchester City, Barcelona, Paris Saint-Germain and Real Madrid in recent months but it appeared as though he was set to remain in Naples at least until after next season.
However, fresh comments suggest that Cavani could very well be considering his options for a possible summer exit.
"I feel good at Napoli, but in football there are many things to be put in consideration," the 26-year old said.
"I can only say I'll give the best for this jersey until the last day I'll wear it."
In an attempt to ward of such clubs, Napoli president Aurelio De Laurentiis recently already slapped a £60 million price-tag on Cavani.
