Platini backs Brazil, England & Spain
"I see three teams who have the quality to win it - in alphabetical order, Brazil, England and Spain," the former French international told a news conference at the UEFA Congress.
"Other teams may be hard to beat but they may not have the potential in absolute terms to win the World Cup."
Brazil have lifted the trophy five times, England were winners in 1966 and Spain are the European champions.
The president of European football's governing body also mentioned Argentina, France, Netherlands, Italy, Ivory Coast and Portugal as teams that could cause trouble for his top three at the finals in South Africa in June and July.
