Poland, who are managed by Belgian coach Vital Heynen, on Sunday take on Brazil, who are undefeated in the competition so far.
With 21 points, the Poles are in second place overall, behind Brazil.
Poland, one of the world's strongest teams, have won all their matches so far in the FIVB Volleyball Men's World Cup except for a 1-3 defeat to the United States last Friday.
