Angel Di Maria (left) scored twice and Lionel Messi was in inspired form as Argentina made it into the Copa America final with a 6-1 hammering of Paraguay.
The Albiceleste, runners-up in last summer's World Cup, will try to win their first continental title for 22 years after a one-sided game which saw Di Maria's Manchester United team-mate Marcos Rojo and Manchester City's Sergio Aguero also on target along with Javier Pastore and Gonzalo Higuain.
Lucas Barrios had cut the half-time deficit to just 2-1 but it is Argentina who will meet hosts Chile on Saturday at the Estadio Nacional in Santiago.
Di Maria said he was "happy for the goals" and added: "It was a great game, a little bit difficult after Paraguay scored, but we managed to control it in the second half."
Messi added: "We knew the goals were coming as soon as we managed to finish some of the opportunities we had.
"We played in the World Cup final and now we are looking forward to winning this cup."
