Assistant coach Oliver Bierhoff has warned Group B leaders Germany that complacency against Denmark could still cost them a place in the quarter-finals.
Germany beat Portugal and Netherlands in their opening two games of Euro 2012 to claim a maximum six points, but could still be eliminated if things do not go their way against the Danes in Lviv on Sunday.
Depending on various permutations of results, any team from the group can still qualify or miss out on the knockout stages. Germany need a point to make sure they advance and Bierhoff has urged his team to remain focused.
"The (2-1) victory over Netherlands felt like a qualification but we have come back down to reality," Bierhoff said. "We are not through yet so we have to be extremely careful against Denmark."
Denmark, who are on three points, would qualify if they beat Germany. Three-time European champions Germany, chasing their first title since 1996, have never gone through a Euro stage with straight victories.
"I do not think about these records," said Bierhoff. "We also won all 10 of our qualifiers. But what is important is that we win our last group game and set up our last eight match here in Gdansk."
