But Argentina themselves were quite lucky to be going through, needing a late goal from Marcos Rojo to steer them into the last 16.
Nigeria had pegged them back to 1-1 via a Victor Moses penalty, and could have had a second spot kick before Manchester United defender Rojo stunned them with a volley off his weaker boot, giving the keeper no chance.
This came after a beautiful goal from Lionel Messi had given the South Americans a 1-0 lead.
They go through, but finish far behind group leaders Croatia, who finished with a perfect nine points after a late Ivan Perisic goal against Iceland.
Given the result in the other game it wouldn't have mattered if they'd won, drawn or lost - they would have gone through on top anyway. But despite that, they caught Iceland on the break as they were desperately chasing a winner that would have put them through instead of Argentina, and the Inter Milan midfielder sealed the win with a classy finish.
So that's four of the eight round of 16 games locked in, and we turn our attention to Groups E and F tomorrow, with plenty on the line. See you then.
