Benevento set the record for the worst start to a season in the top five European leagues - conceding 34 times as they lost their opening 14 games.
The newly promoted side looked set to make that 15 as they fell 2-1 down to AC Milan on Sunday, before goalkeeper Alberto Brignoli ventured up for a corner and leapt to power home an incredible 95th-minute equaliser.
The goal sparked wild celebrations in Benevento's Stadio Ciro Vigorito and set a record as the first strike by a goalkeeper in Serie A for 16 years.
Brignoli, who is on loan from Serie A champions Juventus, dedicated the goal to his Benevento teammates and management.
"I don't believe it," he said. "It is so difficult to score in a situation like that.
"I'm happy for everyone, for the (club) president who never said a word out of place, for the fans who are living a dream and who certainly expected something better.
"Someone from the bench told me to go up, there was nothing to lose, I went to jump and I closed my eyes. It was an instinctive act.
"I jumped like a goalkeeper and not a striker. We have lost so many times in 90 minutes. For once, after months of sacrifice, we've done it."
Newly appointed AC Milan manager Gennaro Gattuso said it "would have been less painful to suffer a stab wound than concede that goal".
He added: "We knew that we would find a Benevento full of desire, unfortunately we paid dearly for the first mistake."
Benevento remain bottom in Serie A and are nine points from safety.
