ATTACK:
Germany has the highest-scoring player in World Cup history in Miroslav Klose. But Argentina has Messi, and two other top forwards to boot. While Messi hasn't scored in the three knockout games, his four goals in the group stage reminded everyone of why he's a four-time world player of the year. Even with Sergio Aguero and Gonzalo Higuain in the team, Messi has always been the key to Argentina's success -- and never more so than in the biggest game of his career. For Argentina to have a chance, Messi will have to create goals -- either for himself or for his teammates.
Germany aren't bad up front either: Klose netted his 16th career World Cup goal against Brazil, and his teammate Thomas Mueller already has 10 in just two tournaments.
Advantage: Argentina
