Nigeria's win gives Group D of the World Cup, already one of the tournament's most intriguing combinations, extra drama going into the last game of the opening round.
Nigeria will be looking to avoid all these calculations by beating Lionel Messi and his compatriots outright, however. Who's going through? Let us know by commenting below.
Fantastic, fantastic, it was a good match, we are very grateful to have won it, it is very good for Nigeria, we are all happy!
- Ahmed Musa has scored each of Nigeria's last four goals at the World Cup, having also bagged a brace in a 3-2 defeat to Argentina in 2014.
The Leicester City striker struck twice in the second half to keep the Super Eagles in with a chance of reaching the last-16. After a swift counterattack, Musa deftly controlled a Moses cross before slamming the ball past Iceland goalkeeper Hannes Halldorsson on the half-volley. "I think Nigeria will beat Argentina, and Croatia and Nigeria will move on to the second stage", an Iceland fan said.
Referee Matthew Conger's decision to award Iceland a penalty following a VAR review - Tyronne Ebuehi was rightly penalized for clipping the heels of Alfred Finnbogason - could not even get Iceland on the scoresheet. Iceland's Gylfi Sigurdsoon fired his penalty over the crossbar.
However, they really turned on the charm today, despite producing a similarly lethargic first-half display. It was not easy to convince them but in the end they did it well.
Iceland are no pushovers though, a fact that is becoming known worldwide now.
- All six of Nigeria's World Cup wins have come against European opposition, and they have kept a clean sheet in five of those victories. Iceland has just a quarter of the population of Buenos Aires, but they didn't let that phase them as they crowded Argentina out of the game.
The match kicked off in temperatures above 30 degrees Celsius but the Volgograd Arena pitch lay in shade to offer some respite from the fierce heat. Sprinting down the left flank, the striker was too quick for Iceland's defence and, with Kári Árnason beaten, he cut inside, weaved beyond the diving Halldorsson to side-foot home.
"We've played Croatia four times in four years and we've often said we're like a married couple trying to get divorced but we always meet up again", he added.
