Sabella's 'great joy' as Argentina reach final
Argentina's coach Alejandro Sabella (C) celebrates with support staff after his team's victory at The Corinthians Arena in Sao Paulo on July 9, 2014 - by Pedro Ugarte
"It's a great joy. It was a very difficult, very close match," said Sabella, whose side will face Germany in Sunday's final in Rio de Janeiro.
"I'm happy. We're in the final. We'll see what we can do with one day less recovery time (compared to Germany) and after penalties.
"Bu we'll give everything: humility, hard work, 100 percent. We'll see if that's enough for us to win."
Argentina goalkeeper Sergio Romero repelled penalties from Ron Vlaar and Wesley Sneijder in the penalty shootout after a cagey stalemate finished 0-0 following extra time at the Corinthians Arena.
Argentina, chasing their third World Cup title, last reached the final in Italy in 1990, when they lost 1-0 to West Germany.
