Former Manchester United trio Edinson Cavani, Sergio Romero and Marcos Rojo were at the centre of the action as Argentina's Boca Juniors beat Brazil's Palmeiras 4-2 on penalties after a 1-1 draw to reach the Copa Libertadores final.
After Cavani opened the scoring for the visitors in the 23rd minute by prodding home a cross from Miguel Merentiel - on loan from Palmeiras - the Brazilians went in at the break a goal down.
But their fortunes quickly changed, with fellow Old Trafford alumnus Rojo sent off for a second bookable offence on 66 minutes, before they equalised in the 73rd with a deflected shot by Joaquim Piquerez from the edge of the box.
With penalties beckoning as a result of no away goals ruling and a 0-0 draw in the first leg, Palmeiras looked to press home their advantage.
The Brazilian club continued to pressure and nearly scored in the last minute of added time with a bicycle kick by Rony, which was saved by Romero, handing his side a lifeline at the death.
Boca once more had Romero to thank, as the game was once more decided on penalties, as it had been in the previous two knockout rounds.
The former United and Sevilla keeper stopped shots by Raphael Veiga and Gustavo Gómez in the shootout, while Palmeiras' Weverton stopped Cavani's shot, only for the Argentine's to win 4-2.
'I'm 36 years old - an age when I like to have fun, and for me penalties are fun,' said Romero.
'You dream about these kind of days when you are a kid and so to live it is a unique, special experience,' Boca midfielder Ezequiel Fernandez added.
'It's history but we know how big we are, how great we are, but it is still a dream.'
Boca's triumph stops a streak of three consecutive all-Brazilian Copa Libertadores finals.
Boca will travel to play another Brazilian club, Fluminense, in the November 4 final at their opponent's home venue, the Maracana in Rio de Janeiro.
The Argentinian giants will seek a seventh South American crown when they take on Fluminense, led by Brazil's national team coach Fernando Diniz, looking for a first Copa Libertadores title.
