Its major founders Fortitudo and Alba having been relegated at the end of 1926–27 campaign, new-founded Roma had to take part to Southern First Division championship (Serie B) for its inaugural season. Nevertheless, the FIGC decided on a special enlargement of first level division re-admitting AS Roma and SSC Napoli. The first ever official matches participated in by Roma was in the National Division, the predecessor of Serie A, of 1927–28, against Livorno, a 2–0 Roma win. The biggest ever victory recorded by Roma was 9–0 against Cremonese during the 1929–30 Serie A season. The heaviest defeat Roma have ever suffered is 1–7, which has occurred five times; against Juventus in 1931–32, Torino in 1947–48, Manchester United in 2006–07, Bayern Munich in 2014–15 and Fiorentina in 2018–19.
