 During the summer of 2008, a club takeover was agreed between Cazzola and an American-based consortium; this was, however, cancelled in the end, following disagreements between the parties, and the club was successively sold to a local group led by new chairman Francesca Menarini, who thus became the second female chairman in the whole Serie A. Arrigoni was confirmed as head coach by the new group, and the start appeared to be particularly impressive, with a surprising 2–1 win at San Siro against Milan thanks to a winning goal scored by Francesco Valiani.The next weeks saw Bologna struggling in the league, however, with eight losses in nine matches.A disappointing 5–1 loss to Cagliari ultimately led the club management to sack Daniele Arrigoni on 3 November 2008 and appoint Siniša Mihajlović as new "rossoblù" boss.
