Genoa fought back twice, so eventually Fiorentina needed an own goal to get the points in a spectacular 3-2 result.
The Viola were flying high in fourth place and looking for a third consecutive victory, welcoming back Alberto Aquilani to the side. Genoa had lost their last two and an injury crisis ruled out Marco Borriello, ex-Fiorentina goalkeeper Sebastien Frey, Francelino Matuzalem, Antonio Floro Flores and Ruben Olivera.
David Pizarro’s shot was accidentally charged down by teammate Aquilani and Andrea Bertolacci blasted over. Stevan Jovetic nodded straight at the goalkeeper, then Aquilani gathered from a promising position inside the area only to volley it into Row Z.
Adem Ljajic should’ve scored when he sprung the offside trap on a smart Jovetic through ball, but at full stretch poked it across the face of goal and past the far post.
Aquilani finally broke the deadlock, although much of the credit went to Ljajic. The youngster ran down the right, got to the by-line and pulled back for Aquilani to tap in the easiest of finishes from point-blank range. Replays show the former Liverpool midfielder shoved Andreas Granqvist out of the way in the build-up.
Tzorvas smothered a Jovetic snapshot, but David Pizarro hit a fierce effort that took a massive deflection to loop over the goalkeeper and land on the crossbar.
Davide Ballardini introduced Bosko Jankovic and Cristobal Jorquera for the second half, but Fiorentina kept pushing and Juan Cuadrado’s cross-shot landed on the roof of the net.
Emiliano Viviano punched a dangerous Juan Manuel Vargas free kick out from under the bar, then the goalkeeper backpedalled furiously to avoid a Stevan Savic own goal, as the header had to be punched away.
From that corner, Genoa got their equaliser, as Daniele Portanova was allowed a free header from six yards to beat Viviano.
A Jorquera screamer flashed inches past the upright as Genoa were pouring forward now, but Tzorvas gave away a goal to restore Fiorentina’s advantage.
The second choice goalkeeper horribly fumbled a Manuel Pasqual cross and allowed Cuadrado to tap in from point-blank range.
Jorquera drilled wide after a Gonzalo Rodriguez error in the box and Genoa drew level yet again in a thrilling game. Jankovic knocked down a cross and Luca Antonelli was totally unmarked to turn in from close range.
Genoa went down to 10 men, as Bertolacci received his second yellow card with 14 minutes left on the clock.
Moments later it was Fiorentina 3-2 Genoa, as a corner found Gonzalo Rodriguez’s header and then got a final touch off Mattia Cassani to fly under the bar.
Another set play saw Savic’s diving header whistle just wide and Tzorvas denied a Mati Fernandez angled drive.
Sent off: Bertolacci 76 (G)
