Germany midfielder Mario Gotze has encouraged his team to show a greater killer instinct in front of goal when they face Ghana on Saturday evening.
A hat-trick from Thomas Muller helped Germany record a 4-0 triumph over Portugal on Monday evening, but despite the wide margin of victory, Gotze has insisted that they should have netted more goals.
The 22-year-old told Kicker: "We could, in some situations, have got more goals against Portugal.
"The result was pretty good, but in the first half, we got a penalty and the red card played into our hands."
Germany will all but secure their place in the last 16 if they can overcome the African nation.
