Ghana landed in Brasilia, Tuesday evening ahead of their defining World Cup Group G match against Portugal.
Kwesi Appiah's team take on the Portuguese on Thursday knowing they must win to stand a realistic chance of progressing to the knockout stages of the tournament.
The Black Stars have earned one point so far in the group, just like their opponents, Portugal.
Ghana needs a massive win against Portugal in Brasilia in the final group match and hope the other fixture between Germany and the United States does not end in a draw.
