Iceland had a chance to get one back but Gylfi Sigurdsson sent a penalty kick way over the Nigeria bar in the 83rd minute.
Nigeria didn't let the fans down, defeating Iceland 2-0, and the qualification will now be decided in the last round of the group stage. I was a bit nervous going into this match, but I must commend Coach Gernot Rohr for accepting criticisms and changing tactics for this game.
The tireless Moses was released down the right and his cross was met by Musa who teed up the ball deftly with the outside of his right foot before unleashing an unstoppable half-volley into the roof of the net.
Wilfred Ndidi almost made it two shortly after, but his well-struck, deflected shot was tipped over by Thor Halldorsson for a corner.
Musa made the game safe with a breathless second, controlling a long ball without breaking stride, beating Kari Arnason then rounding Halldorsson before powering his shot past two covering defenders on the line.
Okocha, speaking on Supersports after the Super Eagles' 2-0 victory over Iceland, noted that it is hard for coaches these days to accept criticisms, but with Rohr doing that, he should be commended.
Excitingly Nigeria, Argentina and Iceland could still join undefeated Croatia in the next round, though the situation remains complicated.
"On the Iceland game". If Iceland wins, Argentina must have a better goal difference to avoid elimination. The Arsenal man relishes representing his country and would certainly become a national hero overnight if he can influence the tie in favour of the Super Eagles.
Obi Mikel was used as an attacking midfielder throughout Nigeria's qualifying campaign but a lacklustre showing in Kaliningrad on Saturday meant he was asked to drop into a more defensive role against Iceland.
The play: Look for a set piece to make the difference.
