Marco Di Vaio took his chance and Siena did not, as the Bologna veteran made the difference in this clash.
This was a relegation tussle between two sides who have impressed at times this season, though results didn’t always support the performances. Panagiotis Kone’ and Franco Brienza were suspended, joining the injured Diego Perez, Simone Loria, Simone Vergassola, Nicola Belmonte and Mattia Destro.
Marcelo Larrondo horribly wasted a promising counter-attack by firing well wide and Daniele Portanova had penalty appeals for a shirt-tug. Bologna defender Antonsson limped off with an injury.
Siena thought they had scored, wearing their all-yellow away strip, on 25 minutes with a Larrondo glancing header, but didn’t count on a spectacular Jean-Francois Gillet reaction save from point-blank range. He was at the near post, but slapped it far enough to knock the ball along the face of goal to go out at the back stick.
Instead, Bologna broke the deadlock moments later with Marco Di Vaio. Gaston Ramirez and Nico Pulzetti created the opportunity, then Alessandro Diamanti’s inspired backheel flick sent Di Vaio clear to lift the finish over an on-rushing goalkeeper from six yards.
Diamanti threatened a second for the home side, while Di Vaio snuck in front of defenders at the near post only to hit the side-netting.
Gaetano D’Agostino’s free kick found a glancing header from Alessandro Gazzi that shaved a coat of paint off the far post.
After the restart Diamanti squirmed past Cristian Del Grosso at the by-line and forced Brkic into a tricky double save at the near post. Diamanti was on fine form and his curling free kick from the left side of the box cracked against the crossbar after skimming Brkic’s fingertips.
Emanuele Calaiò wanted a penalty when Gyorgy Garics charged down his header with an arm, but the referee judged it to be involuntary, as it was from point-blank range. However, Garics did have his arm outstretched.
Diamanti’s angled drive flashed across the face of goal on the counter to skim the upright. At the other end, Reginaldo steered a cross on to the cushioned header of Calaiò to scrape a coat of paint off the post.
