Unfortunately, Nigeria has lost all her previous games against Argentina the other teams in Group D with Nigeria are Iceland and Croatia.
"It is a feasible challenge because of the type of teams".
The draw comes 17 days after Rohr's men stunned Argentina by recovering from two goals down to win 4-2 in Krasnodar.
"I believe that African players have the talent, they have the physical and technical possibilities, but what they are missing is organisation, what they are missing is discipline", said Rohr, who has also coached Gabon, Niger and Burkina Faso.
However, Argentina have come out tops the four times they have clashed with the West Africans at the World Cup - 2-1 (1994), 1-0 (2002), 1-0 (2010), 3-2 (2014).
While Argentina have never met World Cup debutants Iceland on the global stage, they only have to look at England's shock last-16 2-1 defeat at Euro 2016 to know that the Nordic nation will not be pushovers. It had an impressive run to World Cup qualification, beating notable teams like Croatia, Ukraine, and Turkey.
Musa also became the first Nigerian player to score a brace in a World Cup finals match. "We have to be careful, we will have plenty of time to study this team".
They boast several top-class players like captain Luka Modric, Ivan Rakitic, Ivan Parisic and Mario Mandzukic under the guidance of coach Zlatko Dalic. "I hope we keep on making people happy". We need to establish a way and be the Argentina we want to be.
European champions, Portugal, have their hands full in a tough-looking Group B that also features 2010 champions Spain, Iran and Morocco.
While this is not the best possible group the Super Eagles could have fallen into, it is certainly not the worst.
They won a qualifying group that had Croatia, Ukraine and Turkey.
"I think Croatia is a bigger threat in that group".
Familiar foes aside, they will face new opposition in Croatia and Iceland, with their opening game being a first meeting against the Croats.
Argentina did not have superstar Lionel Messi last month. "We aim to progress from the group". "We have to work hard and prepare".
