Even though Slaven Bilic still says that Zaza will prove himself in the Premier League, it is likely that he will be back at Juventus after the season ends.
Zaza is currently on loan at West Ham, but the club must buy him if he makes a number of appearances for West Ham.
If Zaza makes eleven appearances for West Ham, than the English Premier club must pay 20 million euros to Juventus in the end of the season.
It looks like West Ham manager is not interested to use the player and obligate the club to buy him.
If this happens than Simone Zaza will be back at Juventus in the end of the season.
