Real Madrid encountered a setback in La Liga as they were held to a 1-1 draw by Rayo Vallecano, potentially reducing their lead at the top.
Meanwhile, Almeria's struggles continued as they made history for the wrong reasons, becoming the first team to go 28 consecutive league games without a win.
Almeria's draw against Granada marked their 25th consecutive winless game this season, with their last victory dating back to last season.
The draw against Rayo Vallecano came in Madrid's first match since news broke that Kylian Mbappe will leave Paris Saint-Germain at the end of the season, leading to speculation about a move to the Spanish giants. When asked if the rumors had affected his team, Madrid coach Carlo Ancelotti remained tight-lipped.
"When has this team lacked concentration?" Ancelotti said. "It's tough to say anything bad about this team this season."
Joselu put Madrid ahead only three minutes into the match against its southern Madrid rival, but the hosts equalized through a penalty kick converted by Raul de Tomas in the 27th.
The draw moved Madrid six points clear of second-place Girona, which visits fifth-place Athletic Bilbao on Monday.
Third-place Barcelona, which won 2-1 at Celta Vigo on Saturday with a stoppage-time penalty kick converted by Robert Lewandowski, was eight points behind Madrid. Fourth-place Atletico Madrid, which routed Las Palmas 5-0 at home Saturday, was 11 points off the lead.
It was a disappointing result for Madrid against a Rayo team that had lost three consecutive league matches and hasn't won in seven straight.
"We want to win every game but to win the league, you can't lose the games you can't win," Ancelotti said. "Sometimes there are draws that hurt, but they can be a positive step toward winning the league."
Real Madrid remains unbeaten in its last 19 league games, with 14 wins and five draws. It failed to score only once, in a 0-0 draw against Rayo in November.
Madrid was still without Jude Bellingham, who sprained his ankle in the win against Girona last weekend. Brahim Diaz replaced him again, playing alongside Vinicius Junior in attack.
Luka Modric, who hasn't started often this season, was in midfield, while Aurelien Tchouameni again improvised as a central defender alongside Nacho Hernández.
Toni Kroos came off the bench in the second half to make his 450th appearance with Madrid.
Rayo was debuting coach Inigo Perez, the 36-year-old former midfielder who is on his first stint as a head coach. He replaced Francisco Rodríguez following a run of poor results.
The club's winless streak at home is now at 10 consecutive games. It sits in 14th place, eight points from the relegation zone.
Madrid right back Dani Carvajal, who entered the match in the 75th, was sent off deep into stoppage time with a second yellow card.
Winless Almeria
Almeria surpassed the streak of 27 games without a league win that Levante recorded in 2021 and 2022. The worst winless run in a single season had belonged to Sporting Gijon.
Almeria, a Saudi-owned club, went ahead through Marc Pubill in the ninth minute but the hosts equalized with Myrto Uzuni's goal in the 75th.
Granada is second-to-last in the standings, ahead of Almeria and behind Cadiz, which hasn't won in 21 straight league games this season.
La Real wins late
Sixth-place Real Sociedad ended its five-game winless streak across all tournaments with a 2-1 victory at Mallorca thanks to a stoppage-time goal by Mikel Merino.
Japan international Takefusa Kubo also scored for Sociedad. Antonio Sanchez had put Mallorca ahead four minutes into the match.
Mallorca, in 16th place, had Antonio Raillo sent off in first-half stoppage time with consecutive yellow cards - the second after applauding the referee. Mallorca also saw Siebe van der Heyden sent off in second-half stoppage time.
Also Sunday, seventh-place Real Betis was held by 12th-place Alaves to a 0-0 draw at home.
