Real Madrid dropped two points in a 1-1 draw at Osasuna on Saturday in which Jude Bellingham was sent off, but stayed top of La Liga after Atletico Madrid tied 1-1 with Celta Vigo.
The Spanish champions took the lead through Kylian Mbappe before the referee red-carded England international Bellingham for dissent towards the end of the first half.
Ante Budimir levelled for hosts Osasuna from the penalty spot after 58 minutes as Carlo Ancelotti's side endured a third consecutive league match without victory.
Atletico Madrid, who also played with 10 men after Pablo Barrios was dismissed in just the seventh minute, remain a point behind Los Blancos.
Bellingham insisted he was expressing his frustration and not insulting the referee.
"I think you can see clearly in the video, I remember the incident very well, it was an expression to myself," he told reporters. "I'm not even directing myself towards the referee, but obviously there was a misunderstanding. He's believed that I've said [something insulting] to him...
"There was no intent to insult him, there was no insult."
Real Madrid coach Carlo Ancelotti said he was happy with how his team played despite dropping points. "In a footballing sense we started very well, and we finished well despite having one less player," said Ancelotti.
