As it stands, Argentina would miss the 2018 FIFA World Cup if qualifying today as it sits in sixth place in the CONMEBOL standings. On Tuesday, FIFA awarded Peru and Chile all three points from their recent matches against Bolivia after the Bolivians used a player that they weren't allowed to, per Goal Argentina.
Bolivia had beaten Peru 2-0 and drawn Chile 0-0, but used player Nelson Cabrera, a Paraguay-born Bolivian citizen, wasn't eligible to play due to not completing the necessary steps to represent the national team, per Argentina newspaper El Clarin.
As a result, Chile now has 16 points and a better goal differential than Argentina.
The fifth place team in South America when qualifying is done plays a two-leg playoff, while those sixth and below miss out.
That puts Argentina in a difficult spot considering the team has played poorly as of late and matches against Brazil and Colombia on the horizon.
There are eight qualifying games remaining for the South American teams before the World Cup.
