Brazil, Argentina, Mexico and Japan will avoid being drawn in the same group in this year's Olympic Games football tournament, the sport's world governing body FIFA said on Friday.
The nations were named in Pot 1 for the 16-team competition, meaning they cannot face each other during the competition's opening round-robin phase, Xinhua reported.
