Hamza Rafia scored the winner on his debut as Juventus needed extra time to beat Genoa 3-2 and reach the quarter-finals of the Coppa Italia.
A much-changed Juve side were a cut above Serie A strugglers Genoa in the first half at Allianz Stadium on Wednesday, but made hard work of setting up a last-eight tie against Sassuolo or SPAL.
Dejan Kulusevski was outstanding in the opening 45 minutes, scoring inside two minutes and laying on a second goal for Alvaro Morata.
Lennart Czyborra pulled a goal back from out of the blue in an otherwise one-sided first half and Filippo Melegoni later equalised, but 21-year-old Tunisia international Rafia came off the bench to settle the tie late in the first half of extra time.
