Giovanni Trapattoni's assistant coach has indicated his belief that Die Mannschaft's defence may not be as strong as other areas of their team
Joachim Low's side have won their opening two qualification fixtures, defeating Faroe Islands and Austria 3-0 and 2-1 respectively and Tardelli indicated that the Boys in Green would attempt to create problems for them.
"We will not try to play in the same way as Austria (against Germany), but we will try to create some problems, the same problems," Tardelli told reporters.
He continued: "I think if we try and press their defence then it is possible to do some things. Maybe defence is one area where they are not as strong. In the middle and on the wings they are very strong."
Although placing emphasis on exploiting perceived German weakness, the World Cup winner also warned against poor decision-making when attempting to do so.
"We need to press Germany to recover the ball. It is important for us and we need to choose the right moment, because if we choose the wrong time, they can do damage to us," said Tardelli.
Meanwhile, Tardelli also confirmed that Robbie Keane should be fit to play against Germany after picking up a knock in training, while Keith Andrews benefitted from a rest.
The Boys in Green welcome Germany to Dublin on Friday, October 12.
