Argentina are without Javier Mascherano due to his dismissal in the Copa America quarter-final against Uruguay back in July. In his place may step Rodrigo Brana of Estudiantes or Sporting Lisbon's Fabian Rinaudo. Mario Andujar is likely to take the place of Sergio Romero if the Sampdoria stopper does not recover from a knock.
Chile are without two of their key players as Alexis Sanchez and Gary Medel both miss out through injury. Eduardo Vargas has been touted as an ideal replacement for the absent Barcelona forward, however it seems likely that Mauricio Pinilla will be preferred. Claudio Borghi sticks with his favoured 3-4-1-2 formation, giving Matias Fernandez the chance to pull the strings behind the strikers.
Arg: Andujar, Zabaleta, Burdisso, Demichellis, Rojo, Banega, Braña, Di Maria, Sosa, Messi, Higuain
Chi: Bravo, Jara, Ponce, Gonzalez, Isla, Carmona, Vidal, Beausejour, Fernandez, Pinilla, Suazo
