Nigeria v Argentina
June 25 Porto Alegre, 1700
FIFA World Ranking: 3
Head coach: Alejandro Sabella
How they qualified: With hosts Brazil exempt from qualifying, Argentina dominated the South American campaign. They finished way out in front of their rivals, scoring 35 goals in 16 matches.
World Cup pedigree: Twice winners, first on home soil in 1978 when striker Mario Kempes won the Golden Boot, and most recently at Mexico '86 when Diego Maradona gave the greatest series of individual performances in World Cup history. Just don't mention the two painful defeats at the final hurdle, in 1930 (to hosts Uruguay), and in 1990 (to West Germany).
Main man: You may have heard of Lionel Messi. The Barcelona forward is one of the greatest footballers of all time, clearly, but he's yet to produce his best form at international level. Could Brazil 2014 be his tournament?
One to watch: Manchester City striker Sergio Aguero is at the peak of his powers and a good bet to win the Golden Boot. Aguero can thrive in the extra space created when Messi's dribbles distract defences, and he is a ruthless finisher.
What are their chances? Serious. Any squad that boasts attacking talent of the calibre of Messi, Aguero, Angel di Maria, Gonzalo Higuain and Ezequiel Lavezzi is to be feared. If hosts Brazil dream of a victory on home soil, their worst nightmare is to see Argentina lift the trophy in Rio. And the draw was very kind to them – they should walk Group F.
