Goalkeeper Sergio Romero was the hero as Boca Juniors beat Palmeiras 4-2 on penalties after their Copa Libertadores semi-final, second leg ended 1-1 on Thursday, to set up a clash with Brazilian club Fluminense in the final.
Edinson Cavani had put Boca ahead in the 23rd minute but after the Argentine club had defender Marcos Rojo sent off in the 66th minute, Joaquin Piquerez grabbed a leveller only for Boca to triumph in the shoot-out with Romero making two huge saves.
"I'm 36 years old and I'm at an age when I like to have fun, and for me penalties are fun," said former Argentine national team keeper Romero who had helped his team to penalties wins in the previous two rounds.
Boca now have a chance to match Independiente's record of seven Libertadores titles when they face a Fluminense team who are looking for the first triumph in South America's top club competition.
"You dream about these kind of days when you are a kid and so to live it is a unique, special experience," said Boca midfielder Ezequiel Fernandez.
"It's history but we know how big we are, how great we are but it is still a dream," he added.
Fluminense beat Internacional 2-1 on Wednesday to book their place in the November 4 final, which will be held at their home venue, the Maracana in Rio de Janeiro.
