At 13:00 local time in Argentina (18:00 CET), Jorge Sampaoli will reveal his chosen squad to make the trip to Russia.
Just last week, the former Chile boss named a provisional 35-man squad, with 'TyC Sports' somehow getting hold of the final version in the meantime.
Maximiliano Meza, Marcos Acuña and Franco Armani are among the shock names included, which Mauro Icardi, Ricardo Centurion and Diego Perotti all miss out.

Goalkeeper: Sergio Romero, Willy Caballero, Franco Armani.
Defenders: Cristian Ansaldi, Gabriel Mercado, Nicolás Otamendi, Javier Mascherano, Federico Fazio, Marcos Rojo, Marcos Acuña, Nicolás Tagliafico.
