The Super Eagles were drawn alongside Argentina, Iceland and Croatia in Group D.
"It is a feasible challenge because of the type of teams".
A win in that game gives the Super Eagles one leg up on qualification, but a draw would not be the worst result, as long as they claim a win against Iceland in the second game.
"Argentina can not play any worse than they are doing", he told TYC Sports.
Nigeria first played against Argentina in the 1994 World Cup.
As The New York Times' Rory Smith argued, if Argentina can improve its defense, a semifinals appearance in the World Cup could be a slightly pessimistic possibility.
With much of the world cheering on, Iceland's magical spell shattered after they received a 5-2 thumping from tournament hosts France.
Should they finish in the top two, they will meet either the winners or runners-up of Group C, which include 1998 champions France, Denmark and Peru, in the last 16.
Sampaoli said: "These are rivals that are coming with few obligations and a lot of enthusiasm for a unique opportunity as the World Cup is".
"You know that Argentina is a very good team but know that it will be more hard now than in the friendly". We hope we keep on making people happy.
In group G Belgium, Panama, Tunisia and England were merged to battle it out also.
Croatia coach Zlatko Dalic acknowledged that Argentina would be favoured to win the group. "I think we can navigate our way into the knockout stages but it's going to be tough. We can not surprise them like we did the last time, and now they will play with (Lionel) Messi", he added.
Based on the latest Federation Internationale de Football Association rankings Guardian Uk predicts Brazil, Iceland, England and Nigeria to be in the same group. "We aim to progress from the group".
But facing Lionel Messi and Argentina, ranked fourth in the world by Federation Internationale de Football Association, will be another challenge.
Coach Gernot Rohr has warned the Super Eagles to underrate any team and prepare harder for the 2018 World Cup tournament in Russian Federation.
