Atletico Madrid stayed within sight of Barcelona while Real Madrid's attack bailed out its porous defence in the Spanish league on Sunday.
Diego Costa and Kevin Gameiro scored second-half goals to give Atletico a 2-0 win over Athletic Bilbao and keep it seven points behind Barcelona at the top of the table.
Atletico will visit Barcelona on March 4 in what could be its last chance to inject some drama into the title race.
"We will have many important matches after (the game at Barcelona) but this is our path forward, being prepared. We have a competitive team," Atletico coach Diego Simeone said.
Real Madrid remained in a distant fourth place after outgunning Real Betis 5-3 in Seville, four days after they won the first leg of their Champions league last-16 match against Paris Saint-Germain.
MARCO'S MADRID
Marco Asensio continued to impress as the 22-year-old forward scored twice to help Madrid tame Betis.
Asensio headed in after Cristiano Ronaldo's strike was parried by Betis goalkeeper Antonio Adan in the 11th.
Betis pressed Madrid back into their area and Aissa Mandi headed in Joaquin Sanchez's pass to equalize. A counterattack led by Sanchez ended with a shot by Junior Firpo that Madrid defender Nacho Fernandez put into his own net to give Betis a 2-1 lead before halftime.
But Madrid picked Betis apart after Sergio Ramos scored with a header from a corner in the 51st. Dani Carvajal set up Asensio for his second after an inspired run before Ronaldo blasted a fourth goal past Adan in the 65th for 4-2.
Betis weren't through and Firpo crossed for Sergio leon to score with five minutes remaining, only for late substitute Karim Benzema to finish off Betis in stoppage time.
Madrid lost left back Marcelo to a right leg injury in the first half. Madrid have their return leg at PSG in the Champions league round-of-16 on March 6.
"We know the talent they have and they played well, so we can be happy with the win," Madrid coach Zinedine Zidane said. "We started well in the first 10 minutes and then we let our guard down as we do sometimes. But we responded, and responded well."
Madrid still remain 17 points adrift of la liga table toppers and arch rivals FC Barcelona.
SIMEONE STYlE
Atletico's win over Bilbao was textbook Simeone: an ironclad defence and just enough from their attack to take the three points.
Simeone's side suffocated Bilbao, who never threatened goalkeeper Jan Oblak. The hosts, who have conceded a league-low nine goals, recorded their 16th clean sheet through 24 rounds.
Gameiro broke the deadlock at Wanda Metropolitano Stadium shortly after replacing Jorge "Koke" Resurreccion in the 59th. The forward scored from a pass by Antoine Griezmann after Saul Niguez had recovered the ball in midfield to spring an attack that caught Bilbao in disarray.
Costa sealed the result with 10 minutes left when Bilbao defender Unai Nunez failed to intercept a pass by Gameiro, leaving the Spain striker all alone to fire past goalkeeper Kepa Arrizabalaga.
