Not exactly the sexiest names in international soccer, but Nigeria and Iran will be battling for early position behind Argentina in Group F. Let's be honest: this is Argentina's group - everyone else is playing for second place.
Speaking of which, Iran has only one win in its World Cup history (against the United States in 1998) and that likely won't change Monday. Nigeria, too, hasn't seen much success, either, having failed to win a World Cup match since '98.
Something has to give Monday.
But make no mistake: Nigeria has a better-than-good chance to move through to the knockout stage. They must beat Iran, though, as a draw probably won't cut it.
They will be expected to struggle in a group that contains Argentina, Bosnia-Herzegovina and Nigeria, but they can take some encouragement from the leadership of experienced coach Carlos Queiroz.
Meanwhile, Nigeria travel to Brazil full of confidence after romping through the African section of qualifying.
The Super Eagles were unbeaten in their group before they earned a 4-1 aggregate victory over Ethiopia to eventually seal their place at the finals.
The match is likely to feature a number of players who ply their trade in British football, with Ashkan Dejagah, John Obi Mikel, Shola Ameobi, Efe Ambrose and Peter Odemwingie all expected to be involved.
