Iceland face a daunting task when they make their World Cup debut on Saturday in a Group D matchup with Argentina at the Spartak Stadium in Moscow.
The Nordic side hope to duplicate their magical run at Euro 2016, where they marched to the quarterfinals in their first-ever tournament appearance.
However, all the pressure will be on heavily favored Argentina, who have failed to claim a major international tournament victory since their win at the 1993 Copa America.
World Cup betting line: Argentina opened as a -245 favorite (wager $245 to win $100); the total is at 2.5 goals, according to sportsbooks monitored by OddsShark. (Line updates and matchup report)

Argentina vs. Iceland World Cup matchup analysis
Saturday marks the first-ever meeting between these two sides.
Iceland continued their ascension into the ranks of European soccer powerhouses with a strong run through UEFA World Cup qualifying, tallying a 7-1-2 win-draw-loss record in Group I.
However, they have endured a letdown since closing out qualifying with three straight clean-sheet wins, going 2-2-4 in eight friendlies, including losses to a pair of World Cup-bound sides, Mexico and Peru.
An otherwise stingy Iceland defense has surrendered a worrisome 11 total goals in the squad's past four outings. They blew leads in their final two pre-tournament matches, settling for a 2-2 draw with Ghana as +155 favorites on June 7 after storming to a first-half 2-0 lead, and allowing two goals after the 80th minute in a humbling 3-2 loss to rival Norway as +140 chalk on June 2.
Nothing short of domination will be acceptable for Argentina in Saturday's contest.
La Albiceleste routed Haiti 4-0 as massive -2500 chalk in their final pre-tournament friendly on May 29, but they have struggled with consistency since last summer.
Argentina have recorded consecutive wins just once during a 4-3-2 run, including stunning lopsided losses to Nigeria and Spain in recent friendly matches.
However, they are unbeaten in group-stage play in their past three World Cup appearances, compiling an impressive 8-1-0 record since Germany 2006, including four clean-sheet victories.
