"Toni is an important player in Italy. If Napoli do sign him, then it would mean I'd have less playing time and so I would have to leave. It is up to the club, though," Denis told the Corriere del Mezzogiorno newspaper.
"I won't deny it's gratifying to know other clubs are interested in me. It means that despite everything I have done pretty well at Napoli so far.
"It's true I didn't score as many goals as I could have, but a bit of bad luck and circumstances had an influence.
"It's not always easy when your mind is not relaxed, as I only ever played when someone else was injured or suspended. Every game I had to earn my 90 minutes and that was a lot of pressure."
