Latina the following season. However, he was sacked after only a few matches by Sciaretta. He signed a contract with Viterbese for the 2007–08 season, although he could not help the club avoid relegation. He later worked as a football pundit for
Dahlia TV, and subsequently
Mediaset Premium. On 3 March 2021, he was hired as head coach of
Serie D club
Flaminia. He left the club in October 2021 after a poor start to the season. On 10 October 2023, Rambaudi was announced as the new head coach of Serie D club
