Bologna have staged a stunning second-half comeback to snatch all three points from their trip to face Roma this afternoon.
Stefano Pioli's men were helped by a brace from Alberto Gilardino, as well as a goal by former West Ham United forward Alessandro Diamanti.
The hosts went ahead in the fifth minute when Alessandro Florenzi followed in Francesco Totti's shot, which had cannoned off the upright.
Erik Lamela made it 2-0 just ten minutes later and Zdenek Zeman's side looked well in control of the game at half time.
However, quick fire goals from Alberto Gilardino and Alessandro Diamanti stunned the Giallorossi in the second half.
A defensive mix up then allowed Gilardino to pounce and win the game in the last minute of normal time.
