Sergio Aguero has insisted that Argentina do not need to change their approach for Sunday's World Cup final against Germany.

The Manchester City forward admits that he was overjoyed to edge past the Netherlands in a penalty shootout on Wednesday night, and he is certain that Joachim Low's side will be expecting their toughest test in the Maracana this weekend.

"The truth is incredible. I am so happy, we cannot believe it," Aguero told reporters after returning from injury as a substitute in their semi-final triumph in Sao Paulo.

"Germany are always a tough team at the World Cup but we will continue to play our game. Argentina is Argentina. Germany also have a bit of respect for us."

The game on Sunday will be a repeat of the 1986 and 1990 finals.
