Africa has emerged as major source of talent, with players such as Liberian-born Weah, Didier Drogba and Samuel Eto'o playing for some of Europe's leading clubs.
And while an African team had never advanced beyond the quarter-finals of a World Cup, Weah said the 2010 tournament could change that.
"We hope for that, it's not impossible. It's a difficult task but it's not impossible," Weah told reporters. "Ghana just won a junior world cup. Why not?"
"Years ago, we couldn't partake in the best player of Europe and the world. It happened. There is a high possibility that an African team can win a World Cup if it can prepare well."
"I'm sure all of the infrastructure they leave here will give people jobs, allow children to play in stadiums that are being built," he said.
"A lot of kids don't have opportunity to play on grass."
