Lionel Messi-led Argentina begins its 2018 World Cup play on Saturday when it opens up Group D play against underdog Iceland, which is playing in its World Cup.

In the group with Croatia and Nigeria, there are three big points on the line for both of these teams in Moscow. 

Argentina is the presumed favourite of the group but Iceland is a strong pick for a dark horse to make a run in this competition after what the team accomplished at Euro 2016 — making the quarterfinals and upsetting England along the way.

Argentina enters this game with a healthy 23 players, but that isn’t without some tension and question marks.

The team just called up Enzo Perez of River Plate to replace Manuel Lanzini who tore his ACL, and Jorge Sampaoli’s team is also without goalkeeper Sergio Romero, who has started the last two World Cups for the country but got hurt right before the tournament.

Argentina: (4-2-3-1) Caballero; Salvio, Otamendi, Rojo, Tagliafico; Biglia, Mascherano; Meza, Messi, Di Maria; Aguero.

Iceland: (4-4-1-1) Halldorsson; Saevarsson, Arnason, R Sigurdsson, Magnusson; Gudmundsson, Gunnarsson, Hallfredsson, Bjarnason; G Sigurdsson; Finnbogason.

Referee: Szymon Marciniak (Poland).
