Cannavaro voices Real concerns

Fabio Cannavaro doubts whether Kaka and Cristiano Ronaldo will solve the "internal problems" he believes exist at Real.

Cannavaro has spent the past three seasons at Real Madrid but, having not been offered a new contract, will return to his previous club Juventus for the 2009/10 campaign.

And he is not convinced acquiring two world stars will help the club close the gap on treble winners Barcelona.

"The club is going to have to do more because these players will not solve the internal problems," said Cannavaro, who is currently with the Italy squad in South Africa building up to the Confederations Cup.

"The most important thing for the team is to achieve a group mentality."
