Germany manager Joachim Low hopes to be able to exploit 'holes' in an attacking Wales side on Wednesday.
Low takes his men to the Millennium Stadium in World Cup qualifying Group Four, live on Sky Sports 1 & HD1, with their hosts desperate to keep faint dreams of reaching next summer's finals alive.
Wales lost on home soil to Finland at the weekend and have only a lingering mathematical chance of booking a spot in South Africa, making the visit of Germany a must-win encounter.
And therefore Low is expecting John Toshack's outfit to come out with all guns blazing, offering opportunities for his Euro 2008 finalists.
"They must win against us if they want to still have a theoretical chance of qualifying, so they will probably play an attacking game," said the Germany boss.
"The Welsh wanted to improve their place in the table with two home victories, which didn't happen, so against us they will try to show a reaction after the defeat against Finland.
"I hope that will create a few holes at the back for us."
Bayern striker Miroslav Klose is out injured with an ankle problem, and Low insists he will keep faith in Stuttgart's Mario Gomez, despite the forward failing to score in his last 13 internationals to earn criticism from fans.
"There is no problem with Mario," Low added. "I find it unfortunate that a national player is whistled by his own fans rather than being supported.
"I don't worry about Mario, because I know his qualities."
Low has also been boosted by the news that Bastian Schweinsteiger is fit to feature in Cardiff after recovering from a groin strain which ruled him out of training on Monday.
"Bastian has a slight groin strain, but there is no danger of him missing the Wales game," said team manager Oliver Bierhoff.
"The fact he missed training was just a precautionary measure, he just needs another half day of rest."
