Sassuolo confirmed they only need “a few details” before signing Simone Zaza and hope to keep Richmond Boakye.
The striker impressed in Serie B last season with Ascoli, scoring 18 goals in 35 games, and returned to parent club Sampdoria.
However, Juve have already agreed a deal to buy the 22-year-old centre-forward and immediately loan him out to newly-promoted Sassuolo.
“We have already spoken to Juventus, but still need to whittle down a few details to complete the move,” said Sassuolo director general Nereo Bonato on TuttoJuve.
The Serie A new boys also hope to keep Boakye, who is co-owned between Genoa and Juventus.
The 20-year-old Ghanaian forward spent the last two seasons on loan at Sassuolo in Serie B, scoring 21 goals.
“For Boakye we have to wait and see what Genoa and Juve intend to do. At the moment he is at the Under-20 World Cup, so when he returns we’ll discuss the situation.
“He has done well with us over the past two years and we’d like to keep him in the Neroverde jersey.”
