Musa scored two of second-half goals to help the Nigerians beat Iceland 2-0 Friday and move into second place in the group behind already-qualified Croatia.
Nigeria will face Argentina in its final group match on Tuesday in St. Petersburg. If Nigeria wins, it will advance to the round of 16. But if Argentina claims all three points, it can still advance depending on the result of the other match between Croatia and Iceland.
Musa gave Nigeria the lead in the 49th minute after Victor Moses sprinted deep into the Iceland half and curled a cross to the near post. Musa deftly controlled the ball before slamming it past Iceland goalkeeper Hannes Halldorsson on the half-volley.
He doubled the lead in the 75th. Picking up the ball on the left side of the Iceland penalty area, Musa mazed his way past Halldorsson and picked his spot in the Iceland goal.
Iceland had a chance to get one back but Gylfi Sigurdsson sent a penalty kick way over the Nigeria bar in the 83rd minute. The penalty was awarded after a video review showed that Alfred Finnbogason had been brought down by Tyronne Ebuehi.
