Lazio's chances of getting anything from the game were dealt a fatal blow when Antonio Candreva was shown a straight red after 17 minutes for a foul on Stephan El Shaarawy.
After good work by Antonio Candreva, who held the ball up on the edge of the area, Zebina rode Davies' weak challenge and slammed an unstoppable shot that flew past Schwarzer and went in off the far post.
