I am opening a new thread for the men's Club World Championship. Unfortunately, due to the format, the tournament probably won't be as exciting as it was in most of its previous editions.
The 4 participants to play in a round-robin format before setting up the semifinals are:
Cucine Lube Civitanova
Apparently, the Asian champions Shahrdari Varamin from Iran have been banned by FIVB, whereas the runner-ups Panasonic Panthers from Japan have declined the invitation, hence leaving us with the well-known Qatari Al-Rayyan.
