Germany coach Jurgen Klinsmann has hailed the impact of his substitutes after David Odonkor and Oliver Neuville combined to register his side's winner against Poland.
The hosts were repeatedly denied by their neighbours and had looked to have been heading for a disappointing 0-0 stalemate in Dortmund before Neuville struck.
Odonkor looked Germany's liveliest player after coming off the bench and it was from his precision delivery that Neuville stole in at the near post to strike a winner in injury time.
"We wanted to bring more speed into the match and both (substitutes) are fast,'' said Klinsmann. 'They brought some life to the match.
"The whole team tried to put pressure on them the whole time.
''We worked hard and hoped the efforts would bear fruit.''
Neuville was understandably delighted with his crucial goal at the final whistle but was gracious enough to accept that he was fortuitous in being in the right place at the right time.
"Clearly, I was a bit lucky but I think it was well earned,'' said Neuville.
''Now we want to win the next match against Ecuador and we'll be first in the group."
