Lazio coach Davide Ballardini was unimpressed by Alessandro del Piero after he won a penalty for Juventus in yesterday's 1-1 draw.
Lazio went 1-0 down to a spot-kick when Mobido Diakhite was judged to have brought down Del Piero.
Replays suggest he rested a hand on the captain's shoulder, but contact was minimal.
"Let us get straight to the point here and say the penalty was non-existent," commented the Biancocelesti boss.
"You could see straight away it wasn't a penalty. Del Piero had sought contact before and it was clear there was none this time.
"Coming to Turin against an angry Juve and only going behind to a dubious incident is a positive thing. I compliment my players.
"We even tried to win, because towards the end Juve seemed tired and a little frightened."
Stefano Mauri equalised, but it was the introduction of Tommaso Rocchi that changed the game.
