Bologna caused a shock with their first win at the Olimpico in 15 years, as Lazio lost their heads and went down to nine men.
The Biancocelesti were on a high after their derby victory propelled them into third place, even though the injury crisis dragged on. Marius Stankevicius, Stefan Radu, Abdoullay Konko, Cristian Brocchi, Lorik Cana and Tommaso Rocchi were ruled out along with the suspended Lionel Scaloni and Giuseppe Biava. Bologna were also on fine form and missed Simone Loria, Henry Gimenez and the banned Diego Perez, but surprisingly rested Marco Di Vaio.
Alessandro Diamanti went on a strong run from midfield and Luciano Zauri got just enough of a touch to weaken the shot, allowing Federico Marchetti to palm it wide. From that corner, Marchetti did well to parry the Daniele Portanova shot from six yards, but could do nothing as he forced it over the line through the two Lazio defenders.
Diamanti tried to curl in directly from the corner flag and very nearly did it, cracking the top of the crossbar.
Diamanti was pulling the Bologna strings and his cross was volleyed wide by Robert Acquafresca. Stefano Mauri sprung the offside trap on a Francelino Matuzalem ball over the top and his acrobatic overhead kick was well plucked out of the air by Jean-Francois Gillet.
Lazio went so close to an equaliser on 26 minutes, as Mauri chested down a cross and his half-volley forced a tough save from Gillet with his leg at the near post, but nobody was ready to tap in the loose ball.
Instead, Bologna doubled their lead by pouncing on a defensive howler. Marchetti did all he could when rushing outside the box to head the ball away from Acquafresca, but quick thinking Diamanti immediately volleyed into the empty net.
Moments later another Mauri overhead kick was palmed round the upright. Mauri flicked on a cross for Miroslav Klose to prod wide with the outside of his right boot, but Acquafresca fired over at the other end as the Lazio defence was caught out again.
The pressure got to Matuzalem, who lashed out an arm at Diamanti and was shown the straight red card. The contact wasn’t that strong, but the flailing arm was obvious, so the referee took action. Klose was furious, as he had a bloodied lip from an accidental Andrea Raggi elbow moments earlier.
Striker Emiliano Alfaro replaced defender Zauri at half-time. Gillet smothered a dangerous flicked Klose header, but Bologna shot themselves in the foot to let Lazio back into the game!
Matteo Rubin did not communicate with his goalkeeper and the backpass caught Gillet wrong-footed, dribbling into an empty net as the Belgian desperately tried to scramble back. It was a comical moment.
However, moments later Gonzalez was caught out for pace when Ramirez burst past him and the Lazio man clipped his heels on the very edge of the box. It was a free kick and an inevitable straight red card, so Lazio went down to nine men.
The free kick itself was charged down, but Rene Krhin smashed the follow-up across Marchetti into the far bottom corner with a powerful angled drive. It was the Inter-owned midfielder’s debut Serie A goal.
Klose would not give up and fired straight at Gillet, then the German battled his way through and Portanova narrowly avoided another own goal. Antonio Candreva’s cross was redirected off Gyorgy Garics, forcing Gillet into a save at the near post. Late on, substitutes Safir Taider and Di Vaio tried to add to the scoreline. They combined to get the ball in the net, but Taider was flagged offside.
Sent off: Matuzalem 43 (L), Gonzalez 58 (L)
