Mascherano has failed to become a regular at Barcelona since joining the club from Liverpool in a £18million deal last summer.
The midfielder has recently been linked with the likes of Juventus, AC Milan and Roma.
“Mascherano is not moving from Barcelona and there is nothing to say about him going to Italy,” Zandonadi told Italian radio station Mana Mana.
“Mascherano is playing for Barcelona, the best team in the world. What else could he ask for?”
He added: “He wouldn’t even consider his future if Juventus or AC Milan made an offer for him. As for Roma, why would they pay more than Barcelona? He is not leaving.”
