Real Madrid midfielder Kaka has reassured Brazil he is in ''great condition'' after overcoming his injury problems, which have haunted him all season long.
Kaka's participation at the World Cup was threatened by a groin injury that contributed to his loss of form this season. But he insists he will be firing on all cylinders when Brazil play their first match against North Korea on June 15.
''I am getting better every day The injury does not bother me anymore,'' he said. ''I've been doing everything planned so far and by the time we play the opener I will be in great condition.''
Kaka also said that he wanted to prove he was still among the world's best players after an indifferent first year in Madrid.
"It's not my main objective but, yes, I think about it," said the last Brazilian winner of FIFA's player of the year award in 2007. "I hope that at the end of the year a Brazilian player is chosen as the best in the world, because if so (it would mean) Brazil would have won the World Cup."
