Belletti is the understudy to veteran right back Cafu in the squad and as a result has found his opportunities limited.
However should the stalwart captain decide to retire after the tournament Belletti may turn out to be his long-term replacement.
The Sao Paulo man, who turned 26 during the tournament, is known for his attacking play down the flank for his club side.
He is capable of delivering dangerous crosses, and also possesses a handy knack of scoring himself from whatever range.
He is keen to play in Europe and almost joined Valencia last summer but the Spanish side could not agree a fee with Sao Paulo.
