The Leicester outcast came in from the cold with two stunning goals to halt Iceland in their tracks, becoming Nigeria’s record World Cup goalscorer in the process.
Now the struggling Argentines can still qualify for the next round if they beat Nigeria in their final group game next Tuesday and hope that Iceland don’t better their result against group leaders Croatia.
Musa did not score a single Premier League goal for Leicester last season before being sent back on loan to former club CSKA Moscow in January.
Musa’s stunning double came completely out of the blue after a turgid first-half performance from the Africans.
Nigeria are notoriously vulnerable at set-pieces yet conceded a free-kick on the edge of their penalty area after just two minutes.
Fortunately for the not-so-Super Eagles, teenaged keeper Francis Uzoho was able to palm Gylfi Sigurdsson’s shot behind for a corner.
Chelsea wing-back Victor Moses was not quite so fortunate as he copped Birkir Bjarnason’s follow-up volley right in the unmentionables.
