Ahmed Musa's brace gave Nigeria a vital 2-0 World Cup win over Iceland in Volgograd, handing Lionel Messi and Argentina a lifeline as a three-way battle for qualification behind Croatia in Group D goes to the wire.
Musa has scored at two different World Cup finals. Nigeria was the first team in Russian Federation not to have a shot in the first 45 minutes.
The News Agency of Nigeria (NAN) reports that after a goalless first first half, two goals by Ahmed Musa in the second stanza helped to keep the Super Eagles in contention.
Nigeria have battled to earn a 2-0 victory over Iceland at Volgograd Arena in a result that sees the race for second spot in Group D blown wide open.
Iceland, roared on by thousands of fans from the tiny country, kept pushing and were awarded a penalty in the 80th minute when referee Matt Conger used the Video Assisted Referee system to confirm that striker Alfreð Finnbogason had been fouled by Tyronne Ebuehi.
Halldorsson had to tip a deflected Wilfred Ndidi shot over the bar, Leon Balogun header narrowly over and Musa struck the bar shortly before he finished in style for his and and his team's second goal.
But playmaker Gylfi Sigurdsson, Iceland's most gifted player of his generation, blasted his kick high over the bar.
Iceland also conceded the opening goal against Argentina last time out, but they equalised within four minutes and therefore did not have to significantly alter their game plan. No incursion into the final third at either ends for the last few minutes.
With the game heavily poised in the second-half, as both teams were locked in a tense stalemate, Gunnarsson ordered the Icelandic defence up the field for one of his routine distributions into the box. This is not a team who are built to chase games, and Iceland looked short of ideas when they were forced to push forward and take more risks. Despite there formidable World Cup record against European opposition, their was in fact only one previous meeting between these two sides - a friendly in 1981 - and Iceland won 3-0. When this FIFA World Cup got under way, he was still regarded as an impact substitute. Three points against Nigeria would leave them needing only a point against Croatia next week to progress.
