Italian Serie A strugglers Bologna sacked coach Pierpaolo Bisoli on Tuesday and replaced him with Stefano Piolo who becomes the club's fourth coach in the past 14 months.
Bisoli took over at the end of the 2011 season when he replaced Alberto Malesani, who in turn had taken over from Franco Colomba in August 2010 when Colomba was sacked the day before their opening match of the season.
Bisoli's sacking follows the team's failure to win a match so far this season.
After one draw and four defeats Bologna sit bottom of the table. It also heaps further crisis on a club which has had five presidents since December 2010.
Sergio Porcedda, who was sacked for putting the club into debt and left Bologna with a three-point penalty last season, has since had four successors, including current incumbent Albano Gueraldi.
Bologna later announced Bisoli's successor, the 45-year-old Pioli, let go by Palermo days before the start of the current season.
Bisoli is the fourth Serie A manager to be shown the exit after former Italy coach Roberto Donadoni (Cagliari), sacked before the season started like Pioli, and Gian Piero Gasperini (Inter Milan).
