#1 Iceland looked out of sorts after going behind
Iceland struck back against Argentina immediately after going behind but Heimir Hallgrimsson's men looked out of their depths after going behind against the Nigerians. Though they did get into dangerous areas, the final ball was lacking and they seemed incapable of putting a goal past Uzoho for the last 30 minutes.
They also started committing more men forward which opened up a lot of space in Nigeria's attacking third. This ultimately led to the second goal as Musa sprinted past Arnason to complete his brace.
Sigurdsson missing from the spot happened after they went 2-0 down. Iceland are much more than just part-time professional footballers but on the big stage, they're going to have to give a better account of themselves especially during times that can test a team's character.
