The Bianconeri have been reportedly trying to cash in on Alessandro Matri and Fabio Quagliarella in order to fund a move for Napoli wing-back Juan Camilo Zuniga
The Bianconeri have already brought in two new strikers this summer in the form of Fernando Llorente and Carlos Tevez, and given that they also have Vucinic, Sebastian Giovinco, Alessandro Matri and Fabio Quagliarella on their books, it has been suggested they have been trying to hawk their attackers to the highest bidder.
Marotta refused to confirm what players were for sale but did concede that Juve have a problem to address as they look to free up funds and squad space for additional transfers.
"We have a surplus up front," he told reporters on Friday. "But to speak about names is obnoxious, also because consent is essential to any transfer."
Marotta sought to play down mounting speculation that Vucnic might be on the market, but then appeared to suggest that the Montenegrin could be allowed to leave for the right price.
"Speaking about Mirko [like this] is like talking about an entire squad that has brought with it two championships in a row," he claimed. "There are players of great value who must be respected.
"Today, anyway, there are not the right conditions for the boy to be transferred."
It has been claimed that Juve's attempts to sign Juan Camilo Zuniga from Napoli hinge on their ability to offload one of their strikers.
