Start of season Given a normal season where there are no team failures and special promotions, Lega Pro Seconda Divisione would feature 6 teams that had been relegated from
Lega Pro Prima Divisione, 9 teams that had been promoted from
Serie D, and 39 teams had played in Lega Pro Seconda Divisione the year before. Due to twenty-one bankruptcies and non-admissions in the Serie B (one vacancy), Lega Pro Prima Divisione (seven vacancies) and Lega Pro Seconda Divisione (thirteen vacancies) the 2010–11 season was to feature only 3 teams that played in
2009–10 Lega Pro Prima Divisione, 20 teams that played in
2009-10 Serie D, 1 team that played in
Eccellenza and 25 teams that played in
2009–10 Lega Pro Seconda Divisione. The league admitted sixteen teams to fill vacancies created. These teams are: •
