PSG chief angry at Bastia defeat
The capital side were beaten 1-0 in Corsica in a bad-tempered affair with Ronaldinho and Parralo Cristobal being sent off for the visitors.
Perpere was upset at the performance of the officials on the night and felt his side were unfairly treated.
"I come to speak because the players and the coach are quite annoyed by the end of the match and didn't wish to talk," said Perpere. "The match became harder and harder due to some actions noted or not by the referee."
Perpere felt both sending offs were harsh although he would not comment on Ronaldinho's dismissal.
"If Cristobal was sent off, it is not for a bad gesture," added Perpere. "He had the feeling to have been attacked with impunity in first-half.
"I think the scoring didn't show a well-balanced encounter. But we are still aiming for Champions League. However, I won't comment on the Ronaldinho sending off."
