Allegri has given his approval on Ciro Immobile, who came up in Juve's youth system and is owned by Sevilla. But his potential arrival is tied to Zaza leaving and Juventus' strategy would be to acquire him on loan: but it would be a complicated situation since Immobile is aware he wouldn't have much space at Juventus.
I like Zaza but selling him for 30m and getting Immobile on loan with option to buy would be good business. It would also help a lot because he would count as homegrown for the new regulations. And then we could spend big on a CF.
