The Manchester City player feels the Europeans are the clear favourites, but has stressed Argentina will give their all to emerge victorious
The Manchester City attacker feels Joachim Low's men were the team to beat right from the start of the tournament and is happy to head into the game as the underdogs.
Germany impressed in the semi-finals with a 7-1 win over hosts Brazil, whereas Argentina needed penalties to overcome Netherlands in their final-four clash.
"Germany were always the favourites, along with Brazil, to win the World Cup," Aguero said at a press conference. "They continue to be so now. We need to play our own game and it suits us that all the pressure is on them.
"We want to have control of the ball, but we know that Germany are a great team that know each other off by heart having played together for many years.
"It is clear that Argentina always go out to win, but sometimes during the game you have to be cautious. We are all aware of what the objective is and we will leave everything on the field to achieve it.
"We are in the final and we have to play it and win it in whatever way possible. Germany will definitely be worried about us. We have a number of players in attack who can cause them trouble."
Argentina last made it to the World Cup final in 1990, when they were beaten 1-0 by West Germany.
