Juventus, disappointed not to be awarded a penalty when Andrea Pirlo went down under the challenge of Fabiano Santacroce in stoppage-time, stayed second in the table, one point behind AC Milan but with a game in hand.
"We dictated the game and it's a shame not to win an encounter we've dominated in such a way," Juventus manager Antonio Conte told reporters.
"We created many different goal-scoring opportunities and we should have put the ball in the back of the net, but I must say that also today there were several incidents to be reviewed.
"It seems that there's almost fear to award Juventus a penalty.
"We've only had one in our favour, less than everyone. And on average we spend 75 minutes in the opponents' half and we often get into their penalty area. It's a situation that rankles, an alarming statistic. From Siena and Parma, for the single incidents, instead of two points, we would have had six."
