The following season, under manager Luciano Spalletti, Roma won the Supercoppa Italiana over Serie A champions Inter, with De Rossi scoring the decisive goal from a penalty in a 1–0 victory in Milan on 19 August 2007. De Rossi also played a key role as the club defended their Coppa Italia title that season, defeating Inter once again in the final 2–1, on 24 May 2008, although they finished second in Serie A behind Inter.
