Ahmed Musa scored two spectacular second-half goals for Nigeria to keep their World Cup knockout hopes alive in Group D with a 2-0 win.
The Leicester City forward on loan at CSKA Moscow set the Volgograd Arena alight after a breathtaking display. The result dealt Iceland's chances a blow while giving Argentina another chance in the process.
After regaining his place in the starting lineup after starting from the bench for the first game, the forward repaid the confidence of the coach with an exceptional performance.
After a disappointing first game against Croatia, Nigeria had to get back on their feet fast. The number of criticisms that trailed the team's abysmal performance meant they had to up their game against Iceland.
Having attracted fans all over the world because of their elegant and stylish jersey, the Super Eagles translated that title on the field of play against Iceland. It was the sort of performance expected from the African giants.
Spotting the attractive number 7 jersey, the Nigerian struck a volleyed opener four minutes after the restart of the second half. He latched onto a Victor Moses' cross with a superb control in the air before smashing a half-volley into the net.
If you thought the first goal was brilliant, the 2nd goal was genuinely exceptional. It was the kind of goal only seen on a computer video game and remains one of the best strikes of this tournament.
Picture: Musa's gone.
Musa had been a thorn in the flesh of the world cup debutants backline all day with his pace. In fact, his blistering speed was too much for the Icelandic defense as he left them all for dead with a brilliant individual second.
Everton's Gylfi Sigurdsson had an opportunity to give Iceland a lifeline late on in the game with a penalty. However, his effort from the spot went wide off its mark in the 83rd minute.
Tyronne Ebuehi was adjudged to have caught Finnbogason in the box 18. Referee Matthew Conger initially hesitant, consulted with VAR before pointing to the spot.
In the closing stages of the game, Iheanacho fired wide for Nigeria while Finnbogason's angled drive was saved by Uzoho at the other end but time ran out for Iceland.
The result boosted Argentina's faint hopes as well as the Super Eagles', but a victory for Nigeria against Lionel Messi and co on Tuesday would see Rohr's side through alongside Croatia.
Iceland started well with Sigurdsson seeing a free-kick pushed away before curling straight at teenage goalkeeper Francis Uzoho from open play. Nigeria began slowly and failed to muster a shot on goal throughout the first period.
The game was relatively short on quality on the pitch but not on the stands as the fans entertained with the Viking's thunderclap and Mexican waves. But, as the game grew, it became more exciting especially with those world-class strikes from Musa.
MAN OF THE MATCH
Who else but the former Kano Pillars forward. Ahmed Musa was the man of the match and most impressive player on the pitch. His agility and quick feet were responsible for his first goal while his pace and trickery delivered the second.
After failing to start the first game and enduring a difficult spell at parent club Leicester City, the Nigerian had a point to prove, and he took his chances.
Nigeria faces Argentina in the all-important decider at St. Petersburg on Tuesday while Iceland tackles Croatia who has already secured qualification to the next round. The three nations still stand a chance of joining Croatia in the second round.
