Argentina captain Lionel Messi missed a second-half penalty as his side were held to a 1-1 draw by World Cup debutants Iceland in Group D on Saturday.
Sergio Aguero gave the South Americans the lead in the 19th minute with a brilliant finish on the turn from 12 meters.
But Iceland, the smallest-ever country by population to qualify for the World Cup, equalized four minutes later when Alfred Finnbogason swept home a loose ball from close range.
Argentina were awarded a penalty in the 64th minute for a push in the back on Aguero by Hordur Bjorgvin Magnusson.
However, Messi’s weak effort from the spot was saved by goalkeeper Hannes Por Halldorsson.
