The match at Estadio Castelao here Saturday will not be the first time the Boateng brothers clash in a World Cup. They also played when Germany beat Ghana 1-0 at the 2010 edition in South Africa in the group stages.
Ghana, disheartened by their 1-2 loss against the United States, might be looking at an early elimination when they meet three-time winners Germany, who proved their worth against Portugal with a credible 4-0 win.
"It will be a tough match because Germany is the top candidate for Group G and they will play with great confidence after winning 4-0 against a team like Portugal. We will be affected psychologically but we will face them with determination," Ghana striker Asamoah Gyan said.
