Lazio 0 AC Milan 0 (0-0 agg, 4-5 on penalties): Donnarumma the spot-kick hero
Gianluigi Donnarumma was the hero as AC Milan won a dramatic penalty shoot-out 5-4 against Lazio to punch their ticket to the final of the Coppa Italia.
In a two-leg semi-final that failed to produce a goal, the Rossoneri's goalkeeper saved two spot-kicks before Luiz Felipe blazed over wildly in sudden death to hand the initiative to Milan.
And Alessio Romagnoli, a boyhood Lazio fan, coolly stroked home the winning penalty to spark wild celebrations from the visitors - who will face holders Juventus in May's final in Rome.
For Donnarumma it marks the continuation of a dramatic season that has seen him involved in a love-hate relationship with Milan's supporters, who unfurled a banner telling the goalkeeper to "get out" in a 3-0 Coppa Italia win over Verona in December.
But the youngster was pivotal to their success at Stadio Olimpico, saving from Sergej Milinkovic-Savic and Lucas Leiva in the shoot-out, sparing the blushes of Ricardo Rodriguez and Riccardo Montolivo - who failed from the spot for Milan - as well as Nikola Kalinic after the striker missed a sitter in extra-time.
Gennaro Gattuso's side, who are now 13 matches unbeaten, will now head into a huge week that takes in the Milan derby with Inter and the Europa League last-16 first leg against Arsenal, while Lazio will look to rebound against Juve in Serie A.
