Vanuatu need maximum points against Germany to have any hope of reaching the Round of 16 at the FIFA Under 20 World Cup in Korea.
The Melanesians suffered a last minute 3-2 defeat against Mexico in their tournament opener before a 7-0 thrashing by Venezuela on Tuesday.
The Germans are also searching for their first win in Group B, following a loss and a draw.

The President of the Vanuatu Football Federation, Lambert Maltock, expected this would be their toughest match.
"The worst game we will try out best because Germany is professional with all the professional players," he said.
"And they know exactly what to execute so our coach is trying to design a plan to play against Germany and not to concede more goals like we had (against Venezuela)."
Meanwhile New Zealand beat Honduras 3-1 to boost their hopes of reaching the knockout rounds.
The Oceania champions are second in Group E behind France, who they face on Sunday.
The top two team from each group progress to the knockout stage, along with the four best third-placed teams.
