One important fact: Velez used to play on thr Bijeli Brijeg stadium before they got kicked out during the war by the Croatians and they gave the stadium to Zrinjski
The stadiums aren't too good but most of these teams either derive from Serbian or Croatian it seems so it might make for some intense matches and atmospheres. Not that I know just thinking.
You're asking for the arenas of lowest level of basketball in the ninth smallest province of the Philippines. I really, really, really doubt that other than you, anybody else would want that.
