All four teams in group D at the Fifa Under-20 World Cup have three points after tonight's game at Otago Stadium.
Serbia beat a listless Mali side 2-0 to ensure those two teams plus Mexico and Uruguay would have everything to play for on Saturday.
The Serbians, who had lost to Uruguay on Sunday, put the game to rest in the 74th minute.
Three one-touch passes created a simple tap-in for substitute forward Stanisa Mandic to make it 2-0.
It was an oddly flat first half, enlivened by one piece of absolute brilliance.
