The Azzurri see the Colombian as a replacement for Edinson Cavani.
"Jackson Martinez is the right player to replace Cavani," assured his Italian agent Salvatore Fiore on Radio CRC.
"He has great physical strength and exceptional humility. He is proving himself in the Portuguese League, but also in European competition.
"Cavani has already proved what he can give, but Martinez can do even better. The atmosphere of Napoli could really fire up the lad. He had no problems settling in at Porto and I'm sure he'll have none at Napoli."
