Constantine has told the BBC Sport that his side have complete faith in their ability to beat the Black Stars despite their respect for Ghana.
He said: It'll be a very tough game but we're looking forward to it."
The former Malawi coach is banking his hopes on his team's strengths, "we believe we can cause an upset."
He added: "Obviously it's a big game for us here in Sudan, playing against a team like Ghana with all their European stars."
However, Constantine rates his side as the underdogs despite playing at home.
"We'll have to work very hard to try and close them down. Ghana are a side that will punish you for the slightest mistake so we've got to make sure we don't make any silly mistakes."
