PSV Eindhoven defender Stanislav Manolev believes he is being targeted unfairly by referees in the Eredivisie.
The 26-year-old Bulgarian has received nine yellow and two red cards in the Dutch top-flight this season, as well as a booking in a cup game.
Manolev, who joined PSV in 2009 from Litex Lovech, feels he is being picked on by officials.
"I have a feeling that Dutch referees are prejudiced against me," he said.
"Sometimes I think they're showing me cards for irregular breathing and this is embarrassing.
"Referees have been very tough and if I am honest I think over-tough. In my opinion, cards have been handed out a bit too freely."
Manolev, known for his hot temper, quit the Bulgarian national team last September after a row with former coach Lothar Matthaus but later rescinded his decision.
