Dino Lamberti claims that the Switzerland international will fulfil his contractual obligations at the Italian outfit and will play for them for the next three years.
"Inler has three years left on his contract and he's very happy here," he told Radio Kiss Kiss on Tuesday.
"From his point of view, he is 100% committed to the squad and he is very happy to live in the city. He wants to stay. Ever since he arrived, his objective was to play in the Champions League and to win the Scudetto.
"He joined Napoli to win and if he doesn't lift the league title this season then he'll do it next season."
Inler joined Napoli from Udinese in 2011.
