The 1986 and 1990 finals are still two of the most talked about games in football history.
In 1986, Maradona was at the summit of his career and scored all four of Argentina's goals in the quarterfinals and semifinals including the "hand of God" against England. Franz Beckenbauer was in charge of Germany in his first major tournament as coach.
Germany's camp was in disarray, and goalkeeper Uli Stein was sent home for insulting Beckenbauer. Journalists shared a hotel with the players and their nightly escapades became tabloid lore.
But the Germans plodded on and beat France 2-0 in the semifinals, even though the Michel Platini-led French team had been widely expected to face Argentina in the final.
And so, in the noon-time heat of the awe-inspiring Azteca, Karl-Heinz Rummenigge and Maradona led their sides out. The Germany captain was playing injured throughout the tournament and had not scored.
Jose Luis Brown's header and Jorge Valdano's goal on a counterattack gave Argentina a 2-0 lead and Maradona's team appeared to be cruising. Then the Germans struck back.
Rummenigge and substitute Rudi Voeller scored from Andreas Brehme's free kicks and suddenly it was 2-2 with eight minutes to play.
Maradona had been marked by Lothar Matthaeus, who did a good job throughout the match. But with the Germans trying to use the momentum and grab the winner, the ball took a weird bounce in midfield and Maradona sent Jorge Burruchaga racing with a deft left-foot flick. Burruchaga beat the offside trap and Argentina had the title.
Years later, Valdano told Germany's Spiegel magazine that Maradona was so nervous before the final that he called for his mother, Tota.
"'Tota, come and help me, I am afraid, you must help me,'" Valdano described the scene as Maradona broke the pre-match silence in the dressing room.
Four years after that game, Beckenbauer became the first man to win the World Cup as both player and coach.
Germany dominated the final, outshooting Argentina 23-1 but the South Americans held on despite having two men sent off, Pedro Monzon and Gustavo Dezotti, a first for a World Cup final.
The match was decided by a disputed penalty in the 85th minute that was converted by Brehme with a low shot inside the post. Matthaeus had been the designated penalty taker, but he did not trust his shoes and left it for Brehme.
