Preview: Ghana vs Cameroon
Michael Essien will captain the Black Stars in the absence of the suspended John Mensah.
Shilla Illiasu has been passed fit for the game, but coach Claude LeRoy is yet to decide who will take Mensah's place.
Pfister believes his side can upset the hosts.
I will tactically paralyse the Black Stars in Thursday's match," he said.
"I have a track record in this tournament and my primary objective is to beat Ghana."
Junior Agogo is enjoying Ghana's run.
"Over here football is the be-all and end-all, so when we play it helps people to forget about their worries in their life and it brings so many people together," he told BBC Sport.
"It gives us that extra energy to go out and play hard.
"After every game we think, 'it can't get any better', but it's like the sky's the limit at the minute."
