Neymar: Brazil must win London Olympics
Neymar, 20, will be central to the Brazilian challenge and has been part of the team that emerged victorious from tussles with Denmark and USA this week, before falling to Mexico.
Next up for the Santos youngster, though, is Brazil against Argentina on Saturday night, where an Under-23 Seleção side will look to topple Messi's Albiceleste.
"We're trying to find our best training patterns, our style of play and the ideal team for the London Games," Neymar told a pre-match press conference.
"Of course we want to win the friendly, but now is the right time to lose as we do not want to get beat in the Olympics. We are working hard to ensure that at the right time, we can achieve our goal.
"Of course we need to respect Argentina and we have to play our football. We did not come here for nothing; we came here to represent the national team and to get the victory."
