Sao Paolo: Brazil coach Mano Menezes says he has doubts over whether Kaka can force his way into the 2014 World Cup team, putting the onus on the Real Madrid player to prove he is worthy of a spot.
Menezes told Brazilian channel SporTV on Thursday that he thinks Kaka could be key for Brazil in the World Cup, but said "next season will tell if Kaka can still play for Brazil in a World Cup. We all have doubts."
The coach said he has told Kaka he won't be one of the overage players at the London Olympics.
Kaka has played for Brazil in every World Cup since 2002, but his form at Real Madrid has not matched that he showed at AC Milan.
