Team GB's Olympic preparations have got off to a bad start as they trail Brazil 2-0 at half-time in their warm-up match at the Riverside Stadium in Middlesbrough.
The visitors nearly went ahead as early as the fifth minute, but Neymar could only slice his effort wide with the goal at his mercy.
Brazil made the breakthrough seven minutes later as Sandro headed in at the back post from Neymar's cross.
Despite some attacking opportunities for Team GB they were unable to carve out any decent chances.
Instead, the away team doubled their lead on 33 minutes when Neymar converted from the penalty spot after Micah Richards had brought down Hulk in the area.
