Geographical distribution of 2007-08 Serie C1 teams. Serie C1/A teams are depicted with red dots, whereas Serie C1/B ones were represented with yellow.
The 2007–08 Serie C1 season will be the thirtieth football league season of ItalianSerie C1 since its establishment in 1978 . It will be divided into two phases: the regular season, played from September 2007 to May 2008, and the playoff phase from May to June 2008.
The league will be composed of 36 teams divided into two divisions of 18 teams each, whose teams will be divided mainly according to geographical principles.
Teams finishing first in the regular season, plus one team winning the playoff round from each division will be promoted to Serie B; teams finishing last in the regular season, plus two relegation playoff losers from each division will be relegated to Serie C2. In all, four teams will be promoted to Serie B, and six teams will be relegated to Serie C2.
The divisions' composition was confirmed as usual according to latitude. However a number of South teams were included in a division different from their best fitting one in order to reduce the number of potentially heated local derbies. This caused all Tuscan clubs to be included in the Serie C1/B division, otherwise composed mostly by teams hailing from South of Italy, whereas two teams from Campania and two from Apulia were included in the Serie C1/A, which instead features mostly teams from the North.
On April 27, 2008, with one week in the regular season yet to be played, both Sassuolo and Salernitana were mathematically ensured of their respective division titles, thus winning promotion to Serie B for the 2008-09 season.
