Lazio coach Maurizio Sarri was frustrated after defeat to Torino.
Ivan Ilic struck for Toro's 1-0 win.
The refereeing had an impact," Sarri said in his post-match press conference.
The penalty on Hysaj is clear, Torino's goal comes from a throw-in metres inside the pitch. It influenced the game. I wonder how 7 people didn't see these things.
The boys were good, there was a risk of being reduced to 9 or 10 men with these referees.
But then we must evaluate ourselves. We chose this week to work hard and put our foot on the gas for the season finale. Instead, we were lacklustre."
