The two teams will play each other in the semi-finals in St. Petersburg.

"It will be a very tough game for both teams. I think the winner of this match will win the World Cup," Blanc said.

The 52-year-old, who was part of the French squad that won the country's only World Cup title on home turf in 1998, added that the tournament, which will come to an end on Monday, has been a success and that there had been a lot of "beautiful" matches.

Belgium, who have reached their first World Cup semi-final in 32 years, will take on France, finalists in 2006, at the St. Petersburg Stadium on Wednesday at 04:00am AEST.
