Maurizio Sarri has acknowledged the possibility that he may leave Napoli at the end of his current contract, although he has no concerns over the situation.

Napoli sits third in Serie A and faces Sassuolo on Monday (AEST) as it bids to overtake Roma in the race for second place behind Juventus.

Sarri has reformed Napoli since taking over at the start of the 2015-2016 campaign and a key member of his squad, Lorenzo Insigne, recently signed a new long-term contract with the club.

However, despite expressing his delight at securing Insigne's future in Naples, Sarri remained coy in regards to his own situation.

"Napoli are in a strong era and egotistically speaking I am happy to represent it, but for the long-term future there are many issues to be evaluated," Sarri, who still harbours hopes of winning the Serie A title with Napoli, said.

"The club cannot currently plan for the Scudetto, as there are much stronger sides out there. 

"We are growing in terms of mentality, but must work on the almost maniacal attention to detail. This side is ready to fight for its objectives, but we can take nothing for granted.

"My contract expires next year, so seeing as there are clauses in place for me and for the club, in theory it could be my last year.

"It's not something that bothers me that much, as in Serie B and Serie C, my contracts were always about to run out.

"I have no idea and I am not thinking about [my future]. I told Aurelio [De Laurentiis] that the Scudetto cannot be won if certain things don't change, but it is our duty to believe in dreams."
