Germany or West Germany have met Argentina five times in the World Cup finals. The first was in 1958 in the group stage--West Germany won 3-1. They met again in the Group stages in 1966 playing, to a goalless draw.
1986 was their next meeting in the final when Diego Maradona led Argentina to a 3-2 victory.
Four years later they met again in the dullest, most cynical final of all with Germany winning 1-0 with an 85th minute penalty.
They dueled once more in the 2006 quarter final, winning on penalties in a much more entertaining game.
The meet again on Saturday in the quarter finals in what could be a classic.
