Napoli midfielder Marek Hamsik believes that signing for AC Milan would be a "professional development", but his current club appear reluctant to sell to Massimiliano Allegri's side.
Speculation has strongly suggested Hamsik could join Milan this summer, although it remains to be seen if the Serie A champions will meet Napoli's asking price of around €100 million (£90 million).
Slovakia international Hamsik has reiterated his desire to sign for the Rossoneri, but it appears Napoli would prefer to sell the 23-year-old to Milan's fierce city rivals Inter.
"It would be a professional development, so I cannot promise Napoli anything," he said in La Gazetta dello Sport. "They are one of the most successful clubs in the world."
However, Napoli President Aurelio De Laurentiis told the Corriere dello Sport: "He costs €100 million. Besides, if I really do have to sell Hamsik, I'd give him to Inter.
"(Milan vice-president) Adriano Galliani never asked me for him, whereas (Inter president) Massimo Moratti did and was very polite about it.
"He asked me three years ago for Hamsik, then two months ago enquired if anything had changed. I replied no, but I was impressed by his attitude.
"I promised to Moratti that if things do change, then Inter will have a sort of moral option on Hamsik."
