After all relevant championship decisisions in European Leagues are there, here is the list of qualified teams for pool stage and how they qualified:
Italy: A.Carraro Imoco CONEGLIANO (league round winner), Savino Del Bene SCANDICCI (got to the finals), Allianz Vero Volley MILANO (third place)
Turkey: Fenerbahce Opet ISTANBUL, Eczacibasi Dynavit ISTANBUL (both finalists), VakifBank ISTANBUL (third place)
Poland: Grupa Azoty Chemik POLICE, PGE Rysice RZESZOW (both finalists), BKS Bostik ZGO BIELSKO-BIAŁA (third place)
France: LEVALLOIS PARIS Saint Cloud, Neptunes NANTES (finalists)
Germany: SSC Palmberg SCHWERIN, Allianz MTV STUTTGART (finalists)
The champions of their leagues are also eligible:
Ukraine: SC "Prometey" DNIPRO
Serbia: Jedinstvo Stara PAZOVA
Bulgaria: Maritza PLOVDIV
Because Russia is still suspended (it seems at least) instead of the finalists Kasan and Kaliningrad these two might inherit berths:
Hungary: Vasas Obuda BUDAPEST
Slovenia: Calcit KAMNIK
and if one of the above won't play, the next would be VOLUNTARI from Romania, there the new surprise champions (fifth in league round, defeated Alba BLAJ in playoff finals).
There are as usual not many changes in participation to CL 2024: from Italy and Turkey none at all, for Poland Police and Bielsko-Biala replace the both teams from Lodz, for France both are replaced: Paris and Nantes for Volero Le Cannet and Mulhouse and for Germany Schwerin replaces Potsdam (in total 5 of 18). We have to wait, which teams vie via qualification for the two remaining CL berths.
