The Atlas Lions have been handed, arguably, the most difficult group among the five countries representing the continent, as they share Group B with former World Cup champions Spain, reigning European champions Portugal and Iran.
Many football pundits believe it would be a straight-forward fight between the two European countries, with Morocco expected to battle Iran for the third-place but Appiah, who worked with Renard as Ghana's assistant coach during Claude Le Roy's reign in 2008, has a different idea.
"He has gotten a very good defence [in the Morocco team]. He should work on his attacking machinery and they could give Spain and Portugal problems," Appiah told Kwese Free Sports.
"I think he should play compact football [at the World Cup] and demand that his players do what he asks of them. That may give him a chance to qualify from the group," he added.
