I am 90% sure that that match would still be played in Slovenia, like it was in the women's tournament.
There is even a small chance that the draw dictates that Slovenia plays France in the 1/8 finals, and apparently two hosts can't meet before the QF (or even SF?), which would lead to some teams switching places in the draw.
It's a proper mess, I know
Turkey managed to beat Belarus for 3 points but the set they dropped almost surely means that Slovenia will finish second and none of this will be necessary. And I can't say Bulgaria will be favourites against Slovenia in front of a packed crowd in Ljubljana...
Today was a good day even for the ones who don't like the format or the championship in general. Apart from Montenegro vs. Poland, the rest of the matches were mostly and for most parts balanced and interesting. Even Slovakia showed teeth against Belgium.
