Argentina were left to rue a missed Lionel Messi penalty and a decision not to award them a second penalty, despite the use of VAR at this year's World Cup, as they were held to a 1-1 draw by Iceland in Moscow.
Messi was presented with a chance break Iceland's brave resistance from the spot in the 64th minute after Hordur Magnusson collided with Maximiliano Meza in the box, but he put his effort too close to Hannes Halldorsson, who made an easy save.
Shortly afterwards, substitute Cristian Pavon looked like he had been brought down in the area by Birkir Saevarsson, but the referee waved away the Argentine protests.
Replays appeared to show a foul by the Iceland right-back, but the Video Assistant Referee decided against overturning the decision. Just a few hours after France had been awarded a penalty after a video review in their win over Australia, Argentina may have reason to feel hard done by.
On they pressed for a winner, but Iceland's tiring players kept them at bay, ensuring Argentina failed to win their opening match at a World Cup for the first time since 1990.
