Lazio reached the Coppa Italia final and ended AC Milan's hopes of snapping an eight-year trophy drought when a breakaway goal from Joaquin Correa gave them a 1-0 away win in the second leg of their semi-final on Wednesday.
The Argentine struck the only goal of a tense 180 minutes to earn Lazio a place in the final for the third time in five years and heap more pressure on Milan coach Gennaro Gattuso.
Lazio dominated the match at San Siro, and Milan had goalkeeper Pepe Reina to thank for keeping the scoreline down.
"We've beaten Milan and Inter in this stadium, and it's fair that we are in the final," said Lazio coach Filippo Inzaghi, whose side knocked out Inter on penalties in the quarter-finals and will face either Atalanta or Fiorentina.

The first leg had ended scoreless, and there was a lot of tension following Milan's recent 1-0 win over Lazio in the league.
Milan's last silverware was the Serie A title in 2011 and have won just one of its past seven matches in all competitions.
Milan is now under more pressure than ever to finish in the top four of the league and qualify for the Champions League next season.
