Rohr also used the break to substitute defender Bryan Idowu for the more attack-minded Tyronne Ebuehi, a change that nearly immediately gave the team more thrust up front.
"Whenever I play against Argentina, or whenever (Lionel) Messi is playing against me, I score".
On the more positive side of the spectrum is their shock 4-2 win over Argentina last November, but in February they were hammered 4-0 by Morocco and they put in a similarly dismal performance in their World Cup opener.
This was Iceland's first ever defeat in a group stage match at a major worldwide tournament, having previously drawn three and won one of four games.
FIFA World Cup 2018 Iceland v/s Nigeria football match will take place on Friday, June 22.
With this victory, the Super Eagles are second with 3 points behind Croatia with 6 points while Iceland and Argentina have 1 point each. "By the 95th minute we will know who carries the day and, by the grace of God, we are going to work very hard".

The African side will secure a spot in the knockout stage if they beat Argentina on Wednesday (2am Brunei time) in Group D's final round of fixtures.
Nigeria still have to beat Argentina to make sure of extending their stay in Russian Federation but this performance, particularly in the second half, will give them a huge lift for Tuesday's group finale.
But Iceland nearly took the lead in the last minute of the first half, Alfred Finnbogason unable to get a decisive touch on Gylfi Sigurdsson's risky free-kick delivered from the right wing. The Scandanvians, so impressive in beating England at Euro 2016 and taking a point off Argentina, can nearly subject Lionel Messi and co.to elimination if they win today.
"We were ahead of them in our group and we've already beaten them once in Iceland, so we at least have that confidence with us when we play them", he said.
Musa was brought into the starting line-up by coach Gernot Rohr in order to inject pace into Nigeria's attack.
They have failed to score in six of their last 11 World Cup matches.
Victor Moses has been directly involved in 36% of Nigeria's 14 shots at this World Cup so far (3 shots, 2 chances created), more than any other player for the Super Eagles.
Argentina, meanwhile, have to beat Nigeria and also hope Iceland do not win against Croatia, as that could send the South Americans home early, again depending on goal difference.
