Napoli won the Coppa Italia for the first time since 2014 after a shock 4-2 penalty shootout win over Juventus in the final.
After a goalless 90 minutes in Rome, Juventus missed their first two penalties as Paulo Dybala saw his effort well saved by the impressive 23-year-old Alex Meret and ex-Manchester City defender Danilo blazed over the bar.

With Cristiano Ronaldo not getting a chance to take a penalty, Napoli were ruthless from the spot - converting all of their attempts - and it was Arkadiusz Milik who smashed in the fourth to seal the silverware.
Gennaro Gattuso's side had the best chances in the game, with Lorenzo Insigne hitting the post in the first half and Elif Elmas also firing against the woodwork from close range in second half injury-time after Nikola Maksimiovic was denied on the line by Gianluigi Buffon.
The final started combatively with Ronaldo's warning shot, well saved by Alex Meret in the sixth minute, proving the most significant moment early on.
But it was the underdogs Napoli who came closest to breaking the deadlock in the 24th minute when Lorenzo Insigne's swerving 25-yard free-kick destined for the top corner clattered off the woodwork.
Four minutes before half-time Napoli had another flurry of good opportunities. Insigne's goalbound effort was headed clear off the line by Alex Sandro, with Jose Callejon behind him waiting to pounce, before Diego Demme bulldozed his way into the box and saw his low drive bundled away by Buffon.
The second half was similarly cagey with Dybala and Leonardo Bonucci both having attempts from range which did little to trouble Meret in goal.
In the final 15 minutes of normal time, Napoli began to apply more pressure and Buffon was forced into a stunning double save in injury-time. First the 42-year-old parried Maksimovic's bouncing header from a corner before he blocked Elmas' stabbed rebound from point-blank range onto the post.
The final went straight to penalties and Napoli secured the trophy thanks to some fine spot-kick taking.

TALKING POINT - What now for Sarri?
Great expectations were placed on Maurizio Sarri at the start of the season to win every trophy on offer, so to lose against the club from Naples - his home city - will leave a sour taste in the mouth of Juventus fans once the season has concluded. His wait for a first trophy in Italy continues.
With criticism in the Italian media surrounding his tactics and questions over whether he is truly getting the best out of Ronaldo, the former Chelsea and Napoli boss will quickly want to silence the critics by finishing off the Serie A campaign in style and secure the elusive Champions League trophy in August.
