Sergio Ramos said that Real Madrid were not receiving favorable calls from the refs following their 1-0 win over Athletic Bilbao.
Ramos scored a penalty in the match, his 10th goal of the season.
"We aren't going to win or lose the league thanks to referees. Whoever has made mistakes and hasn't achieved their objectives should be critical of themselves. It isn't down to referees that Real Madrid are first," said Ramos.
Zinedine Zidane said that discussions surrounding the refs were taking away from his side's achievements.
"I'm tired of it. It's as if we only win games because of the referees. People should respect Real Madrid and what the players are doing on the pitch."
