The Belgian looks set to remain at Stadio San Paolo beyond the expiration of his existing contract this summer
Napoli president Aurelio De Laurentiis has confirmed that the club have offered talismanic forward Dries Mertens a new deal.
Mertens joined Napoli from PSV for a mere €10 million (£9m/$11m) in the summer of 2013, and has since gone on to write his name in the record books at Stadio San Paolo.
The 33-year-old has racked up 303 appearances for the Gli Azzurri over the last seven years, scoring an impressive 122 goals across all competitions.
His latest strike came during Napoli's 1-1 draw with Inter in the second leg of their Coppa Italia semi-final on Saturday, which saw him move ahead of Marek Hamsik as the club's all-time leading scorer.
Mertens has been a key member of Napoli's squad throughout the 2019-20 campaign, both under previous coach Carlo Ancelotti and current boss Gennaro Gattuso, but his present contract is due to expire at the end of the month.
Chelsea and Inter reportedly expressed an interest in signing the Belgium international in January, and as it stands he will be available on a free transfer from July onwards.
However De Laurentiis insists Napoli have already taken the necessary steps to retain Mertens' services. He told Corriere Dello Sport: “He is a street urchin. We met for breakfast six months ago, it was a revelation, I discovered a special man, intelligent, mentally sharp, a badass.
"Renewing the contract for a 33-year-old footballer is not part of our habits, but with Mertens it was simple, natural. I will say more when he has stopped playing, I would like to find him a role to continue the collaboration."
Napoli director Cristiano Giuntoli revealed that the finer details of Mertens' new contract are in the process of being finalised after Gattuso's side booked their place in Wednesday's Coppa Italia final against Juventus.
“I know the lawyers are working on it, he wants to stay and we intend to keep him, so there’s only one result that can come from that," Giuntoli told RAI Sport.
After Napoli's clash with the Bianconeri, they will look ahead to a meeting with Hellas Verona on June 23 as Serie A gets back underway following the coronavirus-enforced break in the season.
