Bulgaria challenge Poland for first place of pool

Varna, Bulgaria, September 18, 2018 - Defending champions Poland are the only undefeated team of Pool D, but this could change if co-hosts Bulgaria can repeat what they have done nine other times in ten previous World Championship head-to-head encounters with the Poles. The only time Poland beat Bulgaria in a World Championship was in four sets in the semifinals of the 2006 edition in Tokyo.
