West Ham want to sign Simone Zaza on a permanent deal in January, La Gazzetta dello Sport report.
However, Slaven Bilic has upped his interest from a loan deal to signing the striker permanently, having been made aware that Zaza is available in January.
The report claims that Juve want at least £18 million for his services, meaning they will be making a profit on the £13 million they paid for him in the summer, despite the poor form he has shown this season.
Zaza, 24, has played just 10 games all season, starting only three Serie A ties. He has netted five goals, but they have been against the weaker teams in the division, and it is clear he is not a favourite at Juventus Stadium.
West Ham may fancy their chances of signing Zaza due to his current situation with Juve, but the report also indicates that the striker has a preference for his move in January.
It is claimed that the Italian international would prefer a loan move, and he wants to stay in Serie A, as it will give him a better chance of being noticed by Italy boss Antonio Conte ahead of Euro 2016.
Still, it is claimed that Zaza is not rejecting a Premier League move just yet, as he waits to see if the approach interests him.
