Atalanta forward Josip Ilicic came off the bench to score a hat trick in the last 20 minutes and help his side to a 6-2 rout away to Sassuolo on Saturday.
Duvan Zapata headed Atalanta in front from an Alejandro Gomez free kick in the 19th minute and Gomez himself added the second with a deflected shot three minutes before half-time.
There were three goals in a seven-minute spell early in the second half as Alfred Duncan pulled one back for Sassuolo, Gianluca Mancini restored Atalanta's two-goal lead and then Duncan struck again.
With the game on a knife-edge, Ilicic was brought on in the 63rd minute and the Slovenian became the first player to score a hat-trick in Serie A from the substitutes' bench since 2011.
He opened his account with an angled shot in the 74th minute, added a second with three minutes left following an exchange of passes with Gomez and completed his hat-trick on the counter-attack in stoppage time.
