Here, AFP sports looks at five moments which swung the match in the Germans' favour:
Higuain chance - 21 minutes
After a cagey opening, Argentina were handed a glorious chance to open the scoring when Toni Kroos' misplaced header put Gonzalo Higuain clean through on goal.
However, the Napoli striker pulled his shot horribly wide of goal to let Kroos off the hook.
Messi inches from glory - 46 minutes
Lionel Messi's moment to seal his place amongst the greatest players of all time by scoring in a World Cup final seemed to have arrived just after the break as he slipped the German offside trap and lined up a shot on his favoured left foot, but the ball flashed inches past Manuel Neuer's far post.
Neuer's lucky escape - 57 minutes
German keeper Neuer was roundly praised for his sweeper-keeper abilities in the round of 16 win over Algeria, but a rush from his line could have cost his side dear as he clattered into Higuain just inside the area.
However, instead of pointing to the spot and possible showing Neuer a red card, referee Nicola Rizzoli awarded a free-kick to Germany for a supposed foul by Higuain.
Palacio miss - 96 minutes
The chances kept coming for Argentina, but so did the misses as five minutes into extra time it was substitute Rodrigo Palacio who sent the ball wide after controlling Marcos Rojo's cross.
Goetze goal - 113 minutes
The breakthrough was finally broken by Joachim Loew's men seven minutes from the end of extra time as Goetze controlled Andre Schuerrle's whipped cross from the left before stretching to volley past the helpless Sergio Romero.
