Former Juventus and AS Roma star Zibi Boniek is backing incoming Napoli signing Eduardo Vargas to be a big hit.
The Universidad de Chile attacker is expected to join Napoli next month, though no contracts have been signed.
Boniek told Tuttonapoli.net: "I saw him play, I studied him at the Copa Sudamericana and of his first appearances with the Chilean national team.
"I was impressed, I can say that he is really good."
