"First we have to see who gets there because, for instance, Portugal are struggling to qualify," he told the Daily Star.

"But I can say the most important national teams at the moment are Spain, Argentina, Italy, France and England."

Kaka added: "I think England are playing very well under Capello.

"England have a very, very good group of players.

"Of course we know now in football that just talent is not enough. But I think England can have a very good World Cup."
