The Euro 2012 semi-finalists kick-start their World Cup qualifying campaign with what should be a straightforward Group C fixture against a side traditionally seen as one of Europe's whipping boys.
However, the Faroe Islands proved their competitive edge during qualifying for the European Championships with a shock 2-0 victory over Estonia.
And Flick believes goals will not be easy to come by against the tiny Nordic nation on Friday night.
"We need to pay our opponents respect," he said in a press conference.
"The Faroese are very compact and can give away few goals. Big results and wins against them have been scarce in recent years."
Germany are favourites to top a group which also contains Austria, Sweden, the Republic of Ireland and Kazakhstan.
The Irish were also in action in Poland and Ukraine over the summer, although failed to get past the group stage.
They take on Kazakhstan, a team who have struggled to make an impact on world football since gaining their independence 21 years ago.
The Kazakhs are ranked 116 places below Giovanni Trapattoni's team in the FIFA ladder, but captain Kairat Nurdauletov is determined they will give a good account of themselves in Astana.
"We would like to win (against the Irish)," he said. "Only a victory will do. We wouldn't accept a draw.
"Our preparation went well. We have been preparing specifically for the Irish team.
"We feel very good. We want to prove that our football is improving and developing."
The Republic of Ireland are also determined to make a winning start, however, and striker Jon Walters sees no reason why they cannot take maximum points against Kazakhstan.
"These are the games you want to win," he said.
"I don't think any match at international level is easy but hopefully we will go there and get the result that we need because it's not an easy group.
"It was good to be there at the Euros, but we didn't do well and that left us with a sour taste in the mouth.
"Once you have been to an international tournament you want to have that experience again so we have to go on and do well this week and prove that we can qualify again."
Austria and Sweden are not in qualifying action this weekend.
The Scandinavians open their campaign on Tuesday against Kazakhstan while Austria face a derby against neighbours Germany.
