City are said to be keen on the teenage Argentine.
"There are no borders in football anymore," Graziano Battistini told calciomercato.it. "The boy is just looking for an important project.
"It's only normal that these types of rumours are being heard because Nicola has always done well when he has played.
"It's clear that City and other important clubs rate the player, but that doesn't mean that they have made a concrete move for him."
