Well, that was quick.
Nigeria's unblemished defensive record was broken in just the third minute of the match, with Lionel Messi pouncing on a rebound from an Angel Di Maria shot that bounced off the goalkeeper and the post.
The goal was the third for the Barcelona star in as many matches at the tournament.
It could have all gotten out of control rather quickly for the Super Eagles, but Ahmed Musa made sure that didn't happen just seconds later.
What a start.
