The day before Argentina was set to take on Bolivia in CONMEBOL World Cup 2014 qualifying, the news that Sergio Aguero would be unavailable for the game against Bolivia was confirmed. This is in addition to the loss of Angel di Maria, who is arguably first choice for Sabella as well. Without his best wide player and second striker, Alejandro Sabella has to adapt.
More likely than not, he'll be going to a very narrow system that's hard to describe with conventional formation notation. Esteban Cambiasso will probably be the most defensive of three central players, alongside Fernando Gago and Ricky Alvarez, who can also play behind a striker. Lionel Messi will assume his normal place, while Javier Pastore will finally play. The public will finally get to see if the PSG star is what Argentina have been missing over the last two years or if Pastore's national team managers have been right all along.
Bolivia are tough in La Paz, and as they proved in the Copa America 2011, they can be tough against Argentina even in Argentina. Based on that 1-1 draw and the 6-1 thrashing Bolivia handed to Argentina in La Paz in World Cup 2010 qualifying, it's hard to write them off. Argentina did not look good against Venezuela in their last match, and the fans of the Albiceleste are hoping that Pastore can be the antidote that heals what ails them.
