Juventus have confirmed that Italy under-21 forward Domenico Berardi has committed his future to Sassuolo.
The two clubs co-owned the 20-year-old striker and had been due to agree on a permanent transfer between them.
It had been widely expected that Berardi would join the Bianconeri -- but he has instead opted for Sassuolo.
A Juventus statement said a €10 million fee had been agreed for the full transfer.
Berardi has scored 42 goals in 103 appearances for the Neroverdi, but never appeared for Serie A champions Juve.
