"It's good victory for us, but it doesn't mean we've become favorites to win the World Cup", the coach said after the friendly.
"My biggest worry was the way the team played when we were behind". It turned out that the last match against Algeria in the qualifying tournament for the World Cup was held when we already qualified, " Rohr told Sport Express Russia.
Aguero remains in good form, but Argentina will need to do better in the final third if they are to make short work of the Nigerian threat.
"Our team is still work in progress", he said.
The Argentines, parading star players like Sergio Aguero, Javier Mascherano and Angel Di Maria, scored the first two goals of the game.
