In Pamplona, Jude Bellingham received a red card, leaving Real Madrid with ten players, and they were unable to maintain their lead against Osasuna, resulting in a 1-1 draw in LaLiga.
Kylian Mbappé opened the scoring for Madrid in the 15th minute, marking his 11th goal in as many league matches.
However, the situation changed after Bellingham's dismissal, which was reportedly due to his protests five minutes before halftime, according to the Spanish newspaper MARCA.
Following a video review, the referee awarded a penalty to Osasuna and issued a yellow card to Eduardo Camavinga for stepping on Ante Budimir's foot in the penalty area. Budimir converted the penalty in the 58th minute, bringing the score to 1-1 and igniting celebrations at El Sadar Stadium.
This draw puts Madrid's position at the top of the league at risk. Later, Atletico Madrid, currently second in the standings, also drew with Celta Vigo. Barcelona has the opportunity to equal Madrid's points if they secure a victory against Rayo Vallecano on Monday.
Real Madrid's coach, Carlo Ancelotti, received a yellow card early in the match for his protests over what he believed was a handball by an Osasuna player in the penalty area.
The officiating decisions made by referee José Luis Munuera are likely to intensify Madrid's frustrations regarding refereeing in La Liga. Following their defeat to Espanyol, the club sent a critical letter to Spain's soccer federation, expressing concerns over what they deemed "adulterated" officiating that favored other teams.
Osasuna, which previously defeated Barcelona 4-2 in September while the Catalan side was leading the league, has now climbed to seventh place.
