After Recreativo did not exercise the buying option, Sorrentino returned to his country and signed with A.C. ChievoVerona – freshly promoted to the top flight – initially on loan. He played in 32 league games during the season as the team retained their newly found status, and the move was made permanent on 12 June 2009.
