Dries Mertens has been urged to end speculation over his future by signing a new deal to stay at Napoli by team-mates Lorenzo Insigne and Jose Callejon.
And, speaking after Callejon's goal gave Napoli a vital 1-0 away win at Inter, Insigne, who last month signed a new deal until 2022, called on Mertens to follow suit.
"Mertens has a lot of quality and can do well in any role," Insigne said to Mediaset.
"His goals are important, I hope he remains with us so that I get to play alongside him for a long time. He is a great player.
"The club knows how to keep its best players. I renewed my contract for a winning project and I hope he can do the same."
Callejon echoed that message after a San Siro victory that moved Napoli to within one point of second-placed Roma, Mertens having impressed by hitting the post and creating four chances for his team-mates.
"We want champions here," said Callejon. "We all want Mertens to stay, he is happy, in good shape and helps the team.
"We are up there in the table and that is what we wanted. We believe in our chances of finishing second.
"We came to a difficult arena against some big champions, but saw a Napoli side that was hungry and we want to continue like this."
Napoli president Aurelio De Laurentiis said last week that Mertens persuading his wife to remain in Naples would be key to the club's hopes of keeping the 29-year-old.
