Joachim Löw says Germany must create more chances on goal against Portugal.
Löw was pleased with his side's defensive display in Tuesday's 1-0 opening defeat to France, but sees room for improvement in the attacking department.
"We were all disappointed on Tuesday evening after an unlucky own goal cost us the game. But we thoroughly analyzed the game and paid attention to what we would need to do differently against Portugal," said Löw at the pre-match press conference and added:
"We did well defensively against France, but failed to create enough chances on goal. We're optimistic that things will go better against Portugal. We're focused on the game and are confident that we will be able to take home a positive result.
"Tactically, we will need to bring something new to our game, especially in attack. We need to react differently in certain situations and look for other gaps to exploit. These tactical changes have nothing to do with the formation.
"Every player is able to make these adjustments no matter what position they are playing. We were well organized in defense, so we're not planning any massive tactical changes there."
The game will take place at Allianz Arena in Munich tonight at 18 CET.
