Ahmed Musa struck twice to become the first Nigerian to score at two World Cups Friday as the Super Eagles secured a crucial 2-0 win over Iceland, who missed a penalty.
The African side will secure a spot in the knockout stage if they beat Argentina on Tuesday in Group D’s final round of fixtures.
A draw would be enough to eliminate the Argentines but would leave Nigeria’s fate hinging on the outcome of Iceland’s game against Croatia.
Musa, who came into the starting line-up in place of Alex Iwobi, announced himself with two of the goals of the tournament so far.
Musa’s sweetly struck half-volley fired Nigeria into the lead just after half-time before he added a second with 15 minutes to go to make the Group D game safe.
Iceland got a lifeline in the 82nd minute with a VAR-awarded penalty but dead-ball specialist Gylfi Sigurdsson blazed over the bar.
