A substituted Cristiano Ronaldo cut a disconsolate figure as Real Madrid conceded a late equaliser to draw 2-2 at Las Palmas on Saturday.
Earlier, Barcelona shrugged off the absence of the injured Lionel Messi to move to within a point of Madrid at the top of the table as Luis Suarez and Neymar were on target in a 5-0 thrashing of Sporting Gijon.
Ronaldo was replaced moments after helping Madrid go 2-1 in front when Karim Benzema slotted home the rebound after the Portuguese's initial effort was saved.
However, he watched on as Sergio Araujo took advantage of some soft Madrid defending to level as the European champions dropped points for the second time in four days.
Madrid boss Zinedine Zidane insisted that, despite a sub-par display, Ronaldo had been replaced to keep him fresh for Tuesday's Champions League trip to Borussia Dortmund.
"We have another game on Tuesday and he has to rest too now and again," Zidane told Spanish TV station Movistar.
"It is obvious he always wants to stay on the field, but I have to think about my players and particularly Cristiano.
"I have to take him off sometimes and tonight we did it."
Stung by a poor first-half performance in a 1-1 draw with Villarreal in midweek that snapped a 16-game La Liga winning streak, Madrid pressed high from the off and had 17 shots in a wide open first 45 minutes.
Real made the breakthrough just after the half-hour mark when Javi Varas made a fine save from Nacho's low effort, but Marco Asensio followed up to head into an empty net.
The lead lasted just five minutes, though, as Raphael Varane's poor defensive header fell at the feet of Tana, who slotted past the helpless Kiko Casilla.
Varas denied Ronaldo midway through the second half, but substitute Benzema was on hand to turn home the loose ball.
Ronaldo was then replaced by Lucas Vazquez, but didn't acknowledge Zidane as he sulked off the field.
The three-time World Player of the Year has now completed the 90 minutes just once in Madrid's six La Liga games so far this season.
And Ronaldo's mood worsened when Araujo bundled his way past Casilla and Sergio Ramos to slot home the equaliser five minutes from time.
- Suarez magic -
Earlier, Barca overcame a difficult opening half hour to hit five past 10-man Sporting.
Yet, Barca coach Luis Enrique was far from satisfied with his side's display, particularly early in the second half.
"It is a result that doesn't tell the true story of the game -- 5-0 makes it seem easy and simple and that couldn't be further from the truth," he said.
"We were poor at the start of the second half, we didn't kill the game off and Sporting could have got back into the game."
One moment of Suarez magic turned the game in Barca's favour as he raced onto Arda Turan's through ball and flicked the ball past the onrushing Ivan Cuellar before slotting into an empty net.
A fine team goal put the game beyond Sporting moments later as Neymar freed Sergi Roberto down the right and Rafinha met his cross with a powerful near-post header.
More goals flowed in the final 10 minutes after Alberto Lora dived in on Roberto to leave his side a man light.
Paco Alcacer was denied his first Barca goal when he smashed the ball off the underside of the bar, but Neymar mopped up the rebound to make it 3-0.
Roberto was the provider once more for the fourth as Turan powered home his cross at the back post four minutes later.
Denis Suarez then teed up Neymar to sweep home his second of the game two minutes from time.
Sevilla missed the chance to go level with Madrid at the top as they suffered their first league defeat of the season, losing 3-1 at Athletic Bilbao.
On-loan Manchester City midfielder Samir Nasri's first Sevilla goal was in vein as Mikel San Jose, Mikel Balenziaga and Aritz Aduriz's injury time penalty lifted the Basques up to third with a fourth straight win.
