Group A will play host to all-Hungarian encounters between Györi Audi ETO KC and newcomers DVSC Schaeffler, while Ikast Håndbold and Team Esbjerg meet for exclusively Danish affairs in group B.
Romanian powerhouse CSM București are in group A as well alongside regular participants Brest Bretagne Handball, WHC Buducnost and SG BBM Bietigheim. The only team in the group who were not part of last season's competition are IK Sävehof of Sweden.
Fresh faces on group B are MKS Zaglebie Lubin of Poland and Denmark's Ikast Håndbold; they join Krim Mercator Ljubljana, CS Rapid București and Metz Handball.
Each team will play the other seven in their group both home and away. As has been the case in recent seasons, after 14 rounds, the top two teams in each group will qualify directly for the quarter-finals, while the teams that finish in the third, fourth, fifth and sixth places will contest the play-offs.
The lowest-ranked two clubs in each group will be eliminated from the competition at the end of the group phase.
The first round is scheduled for 9-10 September 2023, with the full fixture list to be determined soon.
