One definite absence for Argentina is Fernando Gago, who will be unable to resume his partnership with Javier Mascherano in the middle. The Velez Sarsfield man has suffered a torrid 2013 with injuries, and will be replaced by Lucas Biglia in an otherwise familiar-looking Albiceleste lineup.
Lionel Messi's presence, meanwhile, is still a question mark. The Barcelona star was included in the squad, and reports from training suggest that he will be fit to take the captain's armband against Colombia. With questions remaining over whether he is ready to play, though, coach Alejandro Sabella has refused to confirm his place in the first XI. Erik Lamela or Ezequiel Lavezzi are prime candidates to step in should he be unavailable.
Jose Pekerman is expected to make several changes from the team that was defeated last time around by Venezuela. In an attacking lineup, Cruz Azul striker Teo Gutierrez will enter for Macnelly Torres to partner with Radamel Falcao up front, while Carlos Sanchez could also enter for Edwin Valencia in the middle.
