"It's an act of nervousness or respect, but I think it's respect," Demichelis said.
"For having beaten them in the friendly they respect us more, for our history," he added, recalling Argentina's 1-0 win in Munich in March and meeting in successive World finals in 1986 and 1990 with one victory apiece.
"Many people devalue our victory and our performance," Demichelis told a news conference on Thursday about the March warm-up match in the city where he plays his club soccer for Bayern Munich.
"But this Germany side is the same despite three changes and these same (Argentine) players are those who beat Germany," he said.
"I hope we repeat what we did in that match because Germany did not trouble us. We'll try to keep the ball from them and control it with the good players we have."
"Their team has improved a lot since the World Cup began. I know them all, from the goalkeeper (Manuel Neuer) who can throw the ball to the halfway line to (striker Miroslav) Klose."
