Input: Question: How old was Davide Ballardini when he was replaced by Nedo Sonetti? Passage:More recently, Sonetti joined Cagliari on November 2005, replacing Davide Ballardini, becoming the fourth coach appointed by the Sardinian team in a couple of months. He succeeded in maintaining his job until the end of the tournament, and in leading the rossoblù to maintain a place in the next Serie A; he left Cagliari at the end of the season. On 14 November 2006, Sonetti was appointed to replace Attilio Tesser at the helm of then last-placed relegation-battling Serie A Ascoli. He did not manage to save his side from falling to Serie B, and ended his experience in Ascoli at the end of the season with a second-last place. On November 2007 he returned at Cagliari for his third time, as he was appointed to replace Marco Giampaolo at the helm of the Sardinians. He resigned from his post on 19 December, but was confirmed by the club the next day after Marco Giampaolo rejected to return at the helm of the club. However, Sonetti was sacked only a few days later, after a 5–1 loss to Fiorentina, leaving the team last-placed in the league table, being replaced by Davide Ballardini. From 25 September 2008, he has been called back to Brescia replacing Serse Cosmi. On 19 May 2009 he was sacked himself, following a 2–1 loss to promotion rivals Grosseto that left Brescia in fourth placed, but with only a two-point lead to 7th-placed Triestina.
