The creative pair started together in the Chileans' final practice session before Friday's clash in the Monumental, and are expected to start against the ArgentinesChile coach Claudio Borghi will stay true to his word and seek all three points against Argentina as he prepares an attacking formation for Friday's first World Cup qualifying match.
La Tercera reports that the Argentine-born former Colo Colo coach unveiled a 3-3-2-2 scheme in Thursday's final training session, placing playmakers Matias Fernandez and Jorge Valdivia alongside each other as a creative duo. Fernandez plays in Portugal with Sporting Lisbon, while Valdivia represents Brazilian giants Palmeiras.
Mauricio Pinilla also won the duel with Eduardo Vargas to replace the injured Alexis Sanchez in attack, his aerial ability proving the decisive factor in Borghi's decision to pair him with 2010 qualifying top-scorer Humberto Suazo.
Already missing Sanchez, Gary Medel and Pablo Contreras, there was further bad news for Chile on the injury front. Colo Colo's Esteban Paredes was struggling to regain fitness from a muscle strain, but the striker was finally ruled out on Thursday and did not travel to Buenos Aires.
Argentina and Chile will meet this Friday in the Estadio Monumental, with kick-off scheduled for 20:10 local time (01:10 CET).
Probable Chile XI against Argentina (3-3-2-2):
Bravo; Jara, Ponce, Vidal; Isla, Carmona, Beausejour; Valdivia, Fernandez; Pinilla, Suazo.
