The Barcelona playmaker and the Real Madrid forward along with defender Thiago Silva, who helped Fluminense claim runners-up honours in this year's Copa Libertadores', are named as the three over-aged players in the Under-23 team.

Brazil, who have been drawn in Group C alongside Belgium, New Zealand and hosts China, have never won Olympic gold.

"We called-up three full-backs, three centre-backs and three midfielders," said coach Dunga. "From midfield onwards, there is more diversity, as I was worried about picking up skilful, fast players with presence in the box so we can profit from high balls."

Dunga has been unable to name AC Milan midfielder Kaka after the Italian outfit refused to release him, while Roma defender was also unavaliable Juan.

However, Milan were forced to release Alexandre Pato as he is under 23, while Manchester United's Anderson, Liverpool's Lucas and new Manchester City signing Jo are also named in the squad who will travel to Beijing.

Brazil Olympic squad: Diego Alves (Almeria), Renan (Internacional); Breno (Bayern Munich), Alex Silva (Sao Paulo), Thiago Silva (Fluminense), Rafinha (Schalke 04), Ilsinho (Shakhtar Donetsk), Marcelo (Real Madrid); Anderson (Manchester United), Lucas (Liverpool), Ronaldinho (Barcelona), Diego (Werder Bremen), Hernanes (Sao Paulo), Thiago Neves (Fluminense); Alexandre Pato (Milan), Jo (Manchester City), Rafael Sobis (Betis), Robinho (Real Madrid).
