Roberto Donadoni has left Bologna after three years as the Serie A club's head coach.
The former Italy boss, 54, guided the Rossoblu to 14th place at the end of his first season in charge, but could only deliver back-to-back 15th-placed finishes from his last two campaigns.
Club president Joey Saputo told Bologna's official website: "I consider Donadoni to be a great coach who has made a great contribution to the club, giving us some continuity. But after three years his cycle at Bologna has come to an end."
