Real Madrid warmed up for their decisive Champions League semi-final visit to face Manchester City with a 1-0 win over Getafe on Saturday in La Liga.
The champions' slim victory ensured leaders Barcelona must beat city rivals Espanyol on Sunday in Cornella to be able to clinch the title this weekend.
Marco Asensio broke the deadlock in the 70th minute with a deflected strike from distance, in a game of few chances.
Madrid's win saw them climb provisionally second above Atletico Madrid, 11 points behind Barcelona.
Carlo Ancelotti rotated heavily to keep his key players fresh ahead of the second leg battle with Pep Guardiola's City, following the 1-1 draw last Tuesday in Madrid.
Ancelotti lined up with just three of the side that started the first leg -- goalkeeper Thibaut Courtois, Eduardo Camavinga and Fede Valverde.
Camavinga limped off in the final stages with knee pain sustained in a clash with Juan Iglesias.
Ancelotti said the French midfielder would not take long to recover.
"He twisted his knee a bit, it's a blow, nothing more, he will recover very quickly," Ancelotti told reporters.
"Tomorrow he will rest like the others who played today and I think from Monday he will train with the team, he doesn't have a problem."
Ancelotti added: "The knee is stable, it hurts him a bit now, but the important thing is stability and he has that, 100 per cent."
