[1] But four teams, Roma,[2] Pistoia, Cremona[3] and U.S. Victoria Libertas Pallacanestro,[4] were going through financial trouble which put at risk their participation to the 2020–21 season.

Basket Torino first and then Scaligera Verona[6][7] were invited to the highest league but they both declined, so that the final number of the teams was set to be 16.
