Partenopei confirm a liking for Inler, but it's not enough to warrant a big cash offer for him as president Ayrelio De Laurentiis retrenches for the transfer market
The 26-year-old midfielder has scored two in 31 games for Udinese this season and has proven pivotal in their chase for Europe by taking control of the midfield.
De Laurentiis admits he likes the Swiss international, but landing him will be subject to getting a discount on his price.
"He is a great player and we want him. For us he is worth €9-10 million, but Udinese want €15m," the chief told Radio Marte.
"I don't know if it will be an investment which offers future prospects, but we will look into it further down the line."
Uncertainty may be clouding judgement over Inler, but the Italian appears certain that coach Walter Mazzarri and striker Edinson Cavani are staying.
"Cavani belongs to world football. He can improve still like we have seen this year. He will stay at Napoli, like Mazzarri, and he will improve further," he added.
"Everyone is interested in our players, but no one has asked us for them because they know the answer would be no."
Napoli are second in the league, three points behind Milan, and they meet the Friulani this weekend.
