2017–18 Serie C
The 2017–18 Serie C was the fourth season of the unified Serie C division, the third tier of the Italian football league system.
Teams
A total of 60 teams were expected to contest the league, including 4 sides relegated from the 2016–17 Serie B season, 47 sides who played the 2016–17 Lega Pro season, and 9 sides promoted from the 2016–17 Serie D.On 24 May 2017 Latina, just relegated to Lega Pro from Serie B, was declared insolvent and excluded from the Italian football league system, thus creating a first vacancy in the league composition.
Como did not obtain the necessary federal licence before 30 June 2017, the latest possible date to enrol in the 2017–18 league, and were subsequently excluded creating a second vacancy.
On 6 July, FIGC's Co.Vi.So.C announced that Akragas, Maceratese, Mantova and Messina did not submit a copy of their bank guarantees. Maceratese, Mantova and Messina chose not to file appeals and were excluded from the division, however, Akragas, Arezzo, Fidelis Andria, Juve Stabia and Modena all successfully appealed the initial decision and on 20 July it was confirmed that they would all remain in the division.
On 4 August, Triestina was declared the only eligible club to compete in Serie C as replacement for the excluded ones. This brought the number of clubs that will compete in the 2017–18 Serie C down from 60 to 56.
On 11 August Rende was also declared eligible to compete in Serie C, so the final number of teams will be 57, divided in three groups of 19 teams each.
On 6 November, Modena was officially excluded from the league and dissolved after failing to attend four consecutive matches due to financial irregularities.
