Napoli are threatening to wreck the career of Ezequiel Lavezzi over a row regarding an offer from Liverpool.

The popular striker has said an offer from Liverpool was rejected by the club and above all he is angry that the 'promise' to improve his wages has not been kept.

"Lavezzi can't say anything, nor can his agents," slammed President Aurelio De Laurentiis.

"A man who signs a contract with an agreed upon length and value, which was already improved within seven months of his arrival, cannot ask for more.

"It's not even as if his performances warranted yet another raise throughout the season."

Lavezzi and the rest of the Napoli squad had a wonderful start to the season and were challenging for Champions League places until a massive dip in form for the final months.

"I am surprised by the immaturity of these professionals. It cannot all be based around money, there is also the value of the rapport between people.

"I told [director general Pierpaolo] Marino not to say 'this is football,' or I'll get really angry."
