The German has qualified the Super Eagles for the World Cup with little fuss, and from a group that really should have been much more testing in its scrutiny of the eventual qualifier.
"On the face value, it is a friendly match because there is no trophy on the table for the winner to take home", he said.
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.
With team captain John Obi Mikel expected to return to the Super Eagles' midfield, Wilfred Ndidi is also expected to keep his place with Rohr expected to decide between the duo of Oghenekaro Etebo and John Ogu who were both impressive against Algeria in Constantine last Friday. Argentina would want to win.
But Sampaoli defended his team, saying they did their best to win the encounter. A fan favourite during his years at CSKA Moscow, Musa has fallen on hard times since leaving them for former Premier League champions Leicester City.
The set-piece comes in and Leon Balogun clears, but the ball looks to have struck the defender right on the top of the head. And then extending Nigeria's unbeaten record in World Cup qualifying.
And that was what was truly remarkable about this turnaround: that sometimes, the solution to a complex problem can be starkly simple.
Argentina's Football Association confirmed after the game that the player travelled to a medical facility for further analysis, and later offered a further update on Twitter confirming Aguero had returned to the team hotel.
