Chelsea's newest signing has a big role to play helping Brazil try to win its first Olympic gold medal in men's football.
Oscar will be wearing the No. 10 jersey made famous by Pele and will be in charge of leading the Brazilian midfield during the London Games.
The 20-year-old who calls himself a "modern playmaker" has become the latest young Brazilian to make a move to European football, joining the European champions as soon as the Olympics are over.
The expectations on Oscar are so high in Brazil that he is seen as one of the players guaranteed to be on the team which will try to give the nation the World Cup title at home in 2014.
