Real Madrid's Argentine winger Angel Di Maria says his side are being treated unfairly by referees.
"They expel us for any stupid thing when other teams don't have this problem. There are things that sometimes are not done by mistake," he told a press conference.
The 24-year-old was referring to the recent expulsion of teammates Kaka and Sergio Ramos for two yellow card offences in separate matches.
Kaka was sent off during Real Madrid's goalless draw against relegation strugglers Osasuna on Saturday which left the club trailing La Liga leaders Barcelona by 18 points.
He was first booked for hitting an opponent with a flailing arm when jumping for a header before being shown a second yellow card for preventing a quick free-kick from being taken.
Ramos was sent off during his team's 4-0 victory over Celta Vigo in the last-16 of the Spanish Cup last week.
"It is true that in La Liga things are not going well. But we still have the Spanish Cup and the Champions League. What we want the most is to win both," Di Maria said.
Di Maria, who has struggled to find his best form this season, has netted twice in 18 Liga appearances so far this term.
"I feel very good. It is true that I am not at 100 percent. I am lacking a bit of consistency. But I will try to get back to my previous form," he said.
