A tepid first 45 minutes was flipped on its head in the second half of Nigeria's 2-0 Group D win over Iceland on Friday (June 22), as the Super Eagles took flight on the back of a brace from Ahmed Musa. Nigeria had no shots at the half but ended up with 16 for the game, a reflection of just how much more incisive they were after the break. For Iceland, their dramatic maiden World Cup campaign looks to be coming to a premature conclusion.

Here's the lowdown for the game:

1. THE GOALS

Nigeria 2 (Musa 49th, 75th) Iceland 0

2. THE WOW MOMENT

Ahmed Musa's first goal was a thing of beauty. The Leicester City man, who spent the second half of last season on loan at CSKA Moscow, controlled the ball splendidly off Victor Moses' cross before unleashing a picture perfect half-volley that bulged the back of the net.

3. THE TALKING POINT

Gylfi Sigurdsson's missed penalty in the 80th minute. Just how costly will that prove? Iceland will need all the goals they can get if they want to progress to the knockout stages, because it will come down to goal difference should they and Argentina win their final group matches.

4. THE STAR

Ahmed Musa. With his brace today, Musa broke a slew of Nigeria records: he became his country's top goalscorer at the World Cup (4) and also the first Super Eagle to score at two different World Cups. We've seen again and again just how important it is for teams to have a reliable hitman and Nigeria have that in Musa.

5. WHAT THE RESULT MEANS

Nigeria now control their own fate and will progress to the round of 16 if they beat Argentina in their last match. Draw, and they will have to hope Iceland do not beat Croatia and go through via a superior goal difference. For Iceland, they have to beat group leaders Croatia who have already qualified and hope Argentina do not beat Nigeria by more than a single goal.
