AC Milan reached the Champions League semi-finals for the first time since winning the competition in 2007 as they saw off Serie A rivals Napoli in an incident-packed game.
Milan could face Inter Milan in the last four, with their city rivals going into Wednesday's second leg with Benfica holding a 2-0 lead.
Serie A champions-elect Napoli dominated early on - but Milan won a penalty with one of their first attacks, although Olivier Giroud's spot-kick was saved by Alex Meret.
The veteran Frenchman got the opening goal, though, to make it 2-0 on aggregate when he tapped in following a sensational 70-yard run by Rafael Leao to set him up.
Napoli were then gifted a way back into the game when Fikayo Tomori handled in the box, but visiting keeper Mike Maignan saved Khvicha Kvaratskhelia's penalty.
They did eventually score, through a Victor Osimhen header with seconds remaining in the match - and there was not enough time to create another chance.
Napoli, who are 22 points clear of Milan in the league table, have lost form at a critical time and failed to take a host of opportunities, with 39 efforts across both legs.
