Due to a ten-month ban against head coach Conte for alleged implications of his failure to report match fixing and a similar ban against his assistant Alessio, Carrera became Juventus' caretaker manager in July 2012. In his first official match, he claimed the 2012 Supercoppa Italiana defeating Napoli in Beijing, winning 4–2 after extra time. After Alessio's ban was removed, Carrera returned to the position of technical director, leaving the bench to Alessio.
