Innocent Emeghara was on target again for Siena, but Bologna fought back for a point.
Siena were still buzzing from their shock 3-1 victory over Inter, a result that left them bottom but on a par with Palermo. Massimo Paci was suspended and Nicola Pozzi still injured, while Bologna missed Cesare Natali. The history of this fixture in Serie A was three home wins, one draw and a single Siena victory in 2009.
There was almost a goal in the opening minute, as Gianluca Pegolo scrambled to avoid a corner on Alberto Gilardino, but kept the ball in play and Panagiotis Kone pounced to hit the outside of the post.
An Alessandro Diamanti free kick was flicked inches past the back post, but Gilardino should’ve done better on the counter-attack when stinging Pegolo’s palms.
Gila had the ball in the back of the net, but it was disallowed as Niccolo’ Cherubin was interfering with play in an offside position.
Diamanti nearly scored directly from the corner flag, as Pegolo punched his curling finish out from the near top corner and Christian Terlizzi needed a goalline clearance on the follow-up.
However, very much against the run of play, Siena took the lead moments later. Alessandro Rosina sparked the counter and Alessio Sestu whipped in a cross from the left for Innocent Emeghara’s fine glancing header. He had scored on his Serie A debut against Inter last week.
Emeghara almost completed his brace, flashing an angled drive across the face of goal, but Bologna drew level.
Diamanti provided the assist by rolling a free kick to just in front of the six-yard box where Kone got away from his marker to tap in.
Bologna changed to a 3-4-3 after the break, introducing striker Manolo Gabbiadini for Marco Motta, but Siena lost Angelo to injury.
Diamanti nutmegged Francesco Della Rocca and turned his daisy-cutter just wide, but it ended 1-1.
