Germany coach Joachim Low expects Ireland to rediscover their "incredibly strong" defensive traits when they meet in Friday night's World Cup qualifier in Cologne.
Low is preparing his side for a match where victory would guarantee Germany's berth at the World Cup, but he is not expecting it to be as easy as it was when his troops won 6-1 in the reverse fixture in Dublin last year.
"They did not show their true face in Dublin, we managed to exploit a few weaknesses they don't usually show, but when they go away from home, they defend incredibly well," said Low at a press conference.
"It's grounded in their mentality, with Gaelic games and rugby - they are born to defend and are incredibly strong physically."
Low does not expect Ireland to have changed much following the departure of manager Giovanni Trapattoni either, saying: "It doesn't matter who the coach is or even who the players are, they cannot radically change their system - they are defensive, compact with the maximum physical involvement.
"They like to get the ball towards goal quickly. They may not be world champions in keeping possession, but they get the ball forwards quickly and that's the way they are."
