Coach Joachim Loew was delighted by Germany's fight-back in their 2-2 World Cup draw against Ghana despite their below-par performance.
Miroslav Klose equalled Brazilian legend Ronaldo's record of 15 World Cup goals after coming off the bench to spare Germany's blushes with the equaliser.
Mario Goetze had given Germany the lead before goals from Andre Ayew and Asamoah Gyan threatened to cause a major upset for the Black Stars in Fortaleza.
"I'm actually quite pleased because we showed great moral to come back from 2-1 down in these temperatures," said Loew about the tropical conditions.
"We took the lead, then conceded two goals from nothing.
"The players are completely exhausted, but in the end we had a few good chances against a good, combative and skillful team."
But Loew's enthusiasm failed to mask several deficiencies in the German defence that were exposed by Ghana's determined counter-attacks.
Gyan, whose goal saw him join Cameroon legend Roger Milla as the leading all-time African World Cup scorer with five, said that they had played much better than in the 2-1 defeat to the United States.
"We believed in ourselves today," the 28-year-old told the BBC.
"I think tactically we were perfect today.
"Now we definitely have to beat Portugal. We will have to focus but we believe we can beat them.
