Ghana coach Ratomir Dujkovic admits Sunday's friendly with South Korea in Edinburgh will give him a good idea about how the Black Stars will do in their first experience on the World Cup stage.
Ghana are coming into the Korea match on the back of a 4-1 thrashing of Jamaica in Leicester but Dujkovic believes the encounter with fellow World Cup finalists South Korea will be a sterner test.
He told the Ghana FA's official website: "I am convinced the Koreans will provide us the right challenge and a tip on what to expect in Germany." Meanwhile, midfielder Stephen Appiah believes Ghana can get out of a difficult group in Germany with Italy, the United States and the Czech Republic.Appiah said: "It is our aim to advance to the second round and we will do whatever it takes to get there."
