Brazil have never won Olympic gold in soccer. Perhaps they might change that this year.
Here's the squad Dunga has named to try to take home the prize. It's not a bad roster, though I think Ronaldinho is less than fit.
Goalkeepers: Diego (Almeria, ESP), Renan (Internacional)
Defenders: Marcelo (Real Madrid, ESP), Ilsinho (Shakhtar Donetsk, UKR), Rafinha (Schalke 04, GER), Thiago Silva (Fluminense), Alex Silva (Sao Paulo), Breno (Bayern Munich, GER).
Midfielders: Lucas (Liverpool, ENG), Anderson (Manchester United, ENG), Hernanes (Sao Paulo), Ronaldinho (Barcelona, ESP), Diego (Werder Bremen, GER), Thiago Neves (Fluminense).
Strikers: Robinho (Real Madrid, ESP), Alexandre Pato (AC Milan, ITA), Rafael Sobis (Real Betis, ESP), Jo (Manchester City, ENG).
