Sorry, but your post makes no sense. Why would you expect anything other than an empty arena in Poland when it's not Poland that is playing? The same would be whoever hosted. And if Poland played Kenya in Poland, the arena would also be full.
Having four countries hosting is the only way to improve attendance. The attendance in Slovakia and Hungary has been surprisingly big. Much bigger than how it would be if only one country hosted.
Honestly, this isn't even a FIVB organized event, it's CEV who is the governing body.
😂😂😂😂😂 In Italy for olympics qualifications. And of course even in the world championship the audience was really interested even in non Italian matches. Yeah Lodz arena is really big but a really empty arena like this for and European Champions is objectively embarrassing
