Qualification Usually, to enter, a club needed to be the champions of their country's most recent national championship. If a national association wished to enter more than one club, they could request for permission to do so from the organisers BSWW who would grant or reject the clubs a berth at the tournament depending on the total number of teams already registered. But as was the case in 2020, due to the effect of the
COVID-19 pandemic on the competition, the normal rules regarding qualification were suspended and entry requirements relaxed: the event was opened up to simply any European club that wished to participate.
Entrants 18 clubs from eight different nations entered the event.
