Sassuolo coach Alessio Dionisi says they must keep hold of their strikers after Wednesday's Coppa Italia win against Cagliari.
Sassuolo won 1-0 thanks to Abdou Harroui's strike.
Afterwards, Dionisi said: “It wasn't easy today, but we wanted to make up for the poor performance against Verona and brought home the victory.
“Reaching the quarter-finals is an historic achievement for Sassuolo. It'll be extremely difficult against Juventus, but we don't want to stop here."
On transfer rumours for Gianluca Scamacca and Giacomo Raspadori, Dionisi also said: “Nobody will go. Gianluca will complete the season with Sassuolo, as will Giacomo. We need them, just as they need Sassuolo and this experience in order to grow.
“They are playing more now than they ever have before."
