The Italy international has attracted the interest of the Bundesliga side as it continues its search for a new striker, following the Dutchman's decision to join Spurs.
Wolfsburg is ready to turn its attentions to Juventus attacker Simone Zaza after missing out on Netherlands striker Vincent Janssen.
The Bundesliga side is keen to add some more firepower to the squad ahead of the 2016-17 campaign and had made Janssen the club's main transfer target.
Janssen opted to leave AZ for Tottenham, though, meaning Wolfsburg has to explore other options. The club is keeping a close eye on Borja Mayoral at Real Madrid, but sporting director Klaus Allofs has made it clear that Zaza is an option as well.
