Roma legend Roberto Pruzzo believes local refs have a bias against Jose Mourinho.
In the derby defeat to Lazio on Sunday, the Giallorossi had two players sent off, Roger Ibanez after just 32 minutes and Bryan Cristante in the stoppages.
Lazio's Adam Marusic was also given a red card and the same is true for one staff member each for the two sides.
Pruzzo blamed referee Davide Massa stating, “Roma must ask to have their games refereed by officials outside the Italian federation.
“On Sunday, Roma players received a yellow card after every foul, and Lazio had a yellow card once every five fouls.
"It's a war between Roma and the referees."
