Watch as Musa Barrow and Marko Arnautovic turn it around for the first Bologna win of the season, but Lucas Martinez Quarta was at the centre of attention for Fiorentina.
Defender Martinez Quarta forced an early save and then managed to turn when Riccardo Saponara rolled across the face of goal after a smart bit of skill.
Under a caretaker manager after Sinisa Mihajlovic’s sacking, the hosts turned it around in three minutes with Barrow breaking away from Igor and Arnautovic sent clear by Denso Kasius, although the Viola complained he had fouled Martinez Quarta first.
Igor saw red in stoppages.
