Hosts Chile have progressed to their first Copa America final since 1987. They beat Peru 2-1 in Monday night's semi-final.
Both of the Chilean goals came from Napoli forward Eduardo Vargas. He spent last season on loan at QPR.
Vargas' first trickled over the line. His second, a stunning 63rd minute strike, was hit with true venom.
The Napoli's player's goals were split by an equaliser for Peru. It came via an own goal from ex-Cardiff midfielder Gary Medel.
Argentina play Paraguay tonight for the right to play Chile in Saturday's final.
