Napoli president Aurelio de Laurentiis says he's angrier with Piotr Zielinski's agent than the player.
The Poland midfielder will leave when his contract expires at the end of the season.
De Laurentiis said at a book launch: "How was Zielinski's performance in the last 10 games? Why should I reward someone who told me in the summer that he wanted to stay and then didn't renew.
"I'm not mad at him but with his agent who went to sell him. At this point I have a different consideration.
"If he doesn't train, doesn't put the energy into it and is perhaps afraid of getting injured, what do I have for a player with doubts about his commitment? We have signed (Bournemouth's Hamed) Traore and we have to evaluate him to understand whether to buy him out or not, given that the price is very high."
