フロジノーネ・カルチョ
Rossini returned to Crecesena in June 2011 but left for newly relegated third-division club Frosinone Calcio on 5 August 2011, in a temporary deal with the club having the option to buy half of the registration rights. Rossini was the understudy of Emanuele Nordi and Massimo Zappino. In February 2012, after the closure of winter transfer window, Rossini was allowed to train with home-province club Rimini.
