Brazil coach Mano Menezes has explained why he left Real Madrid midfielder Kaka out of his latest squad. Kaka has been impressive for Real in recent games.

"I think that Kaka can play a big role at the World Cup in 2014," Menezes told Arena SporTV. "I think that in order for that to happen, the next season will be very important.

"2012-13 will say if he can play one more World Cup. And for this to happen, the pre-season will be crucial for him. And it happens that the Olympic Games take place exactly during pre-season in Europe.

"If I believe that he can be at the World Cup and that next season will be crucial, then I have to let him do what he needs to do."
