Brazilian Kaka says he will be fully fit for the soccer World Cup

Brazil playmaker Kaka shrugged off worries about his fitness and form after a difficult season for Real Madrid on Tuesday and said he would be 100% fit at the World Cup.

Kaka, who missed Sunday's La Liga game at Malaga with a hamstring problem, said he would spend four days at Brazilian club Sao Paulo for physical reconditioning before Brazil assemble for a pre-World Cup training camp on Friday in Curitiba.

"I'm going to Sao Paulo to be evaluated, they will see my condition and that I won't have any problems," he told reporters.

"I will be 100% by the World Cup," added Kaka who was also sidelined for six weeks in March and April.

He had a frustrating first season at Real Madrid, failing to find his best form while his team were knocked out in the last 16 of the Champions League and saw arch-rivals Barcelona walk off with the league title.

"It was a very difficult season which I had, but we have examples of players who were not in good form before the World Cup and ended up doing well, so I'm not worried," he said.

Five-times champions Brazil face North Korea, Ivory Coast and Portugal in their first round group at the month-long World Cup finals, which start on June 11.
