Coach Samuel Abimbola believes with more friendly games, the Super Eagles will be ready to face their Group D opponents at the Fifa World Cup.
Gernot Rohr's men begin their campaign against Croatia before trying Iceland and Croatia for size in the draw many feel is tricky for the three-time African champions.
While insisting the friendly win against La Albiceleste is a morale booster before heading to Russia, the former Nigeria youth international wants the Nigeria Football Federation to organise more test games for the team.
“Nigeria should not take their opponents for granted. Friendly matches are different from World Cup matches but that is not to say that we too cannot hold our own against these teams. We need to be afraid of Croatia and Iceland. We should not treat them with kids glove. We need to get opponents that play similar way as Iceland and Croatia,” Abimbola told Goal.
“Iceland are making a serious statement despite having a population of fewer than 400,000 people. We need to prepare very well to stop them. We saw their performances at the last Euro 2016 when they shocked England."
“With quality friendly games, I believe with that we will be ready for our opponents at the World Cup.
“The victory over Argentina can give us confidence that they are beatable. It is not for us to rest on our oars because we beat Argentina in a friendly game. We must not relax because we still have many months to the World Cup finals and so many things will have taken place before then.
Eagles will be playing Argentina on the fifth occasion next year in Russia out of the six times that have taken part in the World Cup and have lost all but they are facing Croatia for the first time while Iceland are making their debut appearance at the World Cup.
