Palermo are through to the Coppa Italia quarter-finals after beating Chievo 1-0, having rattled the woodwork three times.
These two sides had also met in Serie A on Sunday, a 0-0 draw at the Stadio Bentegodi, but they crossed paths again in Sicily this afternoon.
Both sides threatened to break the deadlock with Salvatore Sirigu parrying efforts from Bojan Jokic and Davide Moscardelli.
At the other end, Lorenzo Squizzi kept out Fabrizio Miccoli's free kick and thanked Simone Bentivoglio for a goalline clearance to deny Cesare Bovo.
The Rosanero stepped up the pressure after the break with Miccoli's curler thumping the crossbar.
Bovo also rattled the woodwork following a Josip Ilicic counter-attack and Pajtim Kasami horribly wasted a great opportunity set up by Miccoli.
Kasami was again wasteful by hitting the frame of the goal for a third time.
With extra time looming and 10 minutes left on the clock, Carlos Rincon brought down Miccoli and the striker got back up to convert the decisive penalty.
