Ronaldo believes Mario Balotelli “can make the difference at the World Cup, if he behaves himself.”
The former Inter, Real Madrid and Milan striker will be taking part in the Brazil 2014 finals draw on Friday at 16.00 GMT.
“Italy are traditionally a team to be feared in these tournaments,” he said at a Press conference in Costa do Sauipe.
“Even when they don’t necessarily play that well, they still often get to the semi-final or the Final.
“Balotelli is a great champion and can make the difference at the World Cup, if he behaves himself.”
