#2 Argentina's defence needs improvements
The Argentine defenders must have been counting themselves lucky. Gylfi Sigurðsson had not been sharp with his set-pieces which rarely troubled the defenders and their goalkeeper. Even when Iceland pushed forward with their counter-attacks, the Scandinavian nation pulled off quite a number of stray and long shots. Argentina could really have conceded more than a single goal. According to Opta statistics, Iceland failed to register a single shot in the second half and this shows that the team simply did not give Argentina much problem. If they did like in the first half, the Argentines could suffer badly.
As a whole, La Albiceleste's defence looked uncertain and unsure of what's going on. The defenders panicked as soon as they were unable to clear the ball. Even though the most experienced international players on the team were the defenders, the likes of Nicolas Otamendi and Marcus Rojo were unable to make much of a difference.
At the same time, the full-backs seem to be unsupportive of their side's attack, leaving all the job to the midfielders and forwards. If that is Argentina's style of playing, then the defenders would have to make sure that they remain alert throughout the match. There had been too many occasions where the Argentines were not pressing the Icelanders tight enough, giving their opponents to quickly turn over the possession and spark an attack.
