"You don't think about that pressure on the field," said Schurrle, who has now scored five goals in his past five international appearances after his extra-time strike against Algeria on Tuesday. "You are in the match and you just have to win the duels."
Schurrle came off the bench as a halftime substitute in Porto Alegre and made a difference with his strong running and direct style. He must now hope he is in line for a starting place against France having replaced the ineffective Mario Gotze.
"It was good for me, of course," Schurrle said. "I scored the first and I was involved in the second, so I am happy that we got through because it was a difficult match."
Given the unconvincing nature of the victory against the Algerians - with Low struggling with injuries and illness and fielding four centre-halves in defence - there are fresh doubts in the German camp.
Low has already described the quarter-final against France at the Maracana on Saturday as a "classic" encounter and it will revive memories of the extraordinary semifinal between the countries in the 1982 World Cup when Germany came from 3-1 down in extra time to win on penalties.
Schurrle acknowledged it would be difficult for them to become the first European nation to win the World Cup in South America.
Germany will have to beat France and then, possibly, Brazil (or Colombia) in the semifinals and then Argentina in the final.
"We will have to do it the hard way, but if you want to win the World Cup you have to play against every top team," Schurrle said. "It's difficult for us but maybe it's good because then you'll be under pressure all the time because every match is going to be tight."
