Nigeria's win, their first at a World Cup finals since 1998, leaves them as favourites to join Argentina in the second round.
Argentina are on six points after beating Iran 1-0 earlier on Saturday to leave the Iranians on a point while the Nigerians are on four points.
Nigeria play Argentina in their final group game on Thursday -- the Africans lost 2-1 on the previous occasion they played the South American side in the group stage in the 1994 finals.
