Parma President Tommaso Ghirardi has launched an attack on Serie A's referees after seeing three of his players sent off against Napoli.
The Crociati are just a point above the relegation zone with four games to go after their 2-1 defeat and believe their great escape is being hampered by poor refereeing.
"The bitterness is great. We are at the end of the season and we are being made to suffer a series of negative episodes. Those of Sunday were the worst," said Ghirardi.
McDonald Mariga, Giulio Falcone and Andrea Gasbarroni were all red carded and Napoli were awarded a contentious penalty.
The visitors could also have had more than one of their won men sent off in an explosive finale to the tense encounter.
"Gasbarroni committed an ugly foul and he will be punished by the FA, but all the rest were non-existent.
"The global state of refereeing is insufficient," stormed the Gialloblu chief, who doesn't believe his players are being treated to a backlash from Francesco Totti's insolence last week.
Totti swore at referee Nicola Rizzoli for blocking his path and was yellow carded and fined a small amount, provoking outrage and claims he should have been dealt with more severely.
"I don't believe that is why, because since the beginning of the year there have been problems. There is little balance, which is the fruit of immaturity on the referee's part.
"The refereeing class is always under observation and commits many errors because of it," opined Ghirardi.
"Parma are playing like champions and the referees are sending us toward relegation," insisted the Swiss businessman.
"We have made many mistakes and we are young, but if we consider the difference four or five points make I believe referees have carried away much more."
The Gialloblu face relegation rivals Reggina on Sunday and still have to play Fiorentina and Inter before the end of the season, making their first relegation in 18 years a real possibility.
