Diégo Costa scored twice as Atlético Madrid beat Valencia 3-0 to maintain their 100% home record this season and keep pace with Barcelona at the top of La Liga.

The in-form forward broke the deadlock on the hour and Raúl García added a second moments later with Valencia's resistance broken.

Costa then missed a penalty but converted a second with nine minutes to go, his 17th league goal of the season putting him level with Real's Cristiano Ronaldo at the top of the scoring charts.

"You need to show personality and fight for your achievements so after missing the first penalty I wanted to take the second," Costa said. "Valencia played well in the first half and we knew that we had to do a bit more especially in attack which we did."

Atlético are level on 43 points with Barcelona who beat Villarreal 2-1 on Saturday while third-placed Real Madrid lost further ground following a 2-2 draw at Osasuna.

Atlético started slowly with Gabi Fernández and Tiago Cardoso quiet in midfield and there were only flickers of life from their forwards.

They upped their level after half-time and Costa dribbled in from the left wing with Víctor Ruiz backing off before slotting home.

Minutes later they were further in front when García knocked in a loose ball in the area. Costa was then upended in the area by Ruiz and took the penalty himself but Diego Alves saved well with his feet.

Atlético were now ripping open the Valencia defence and Antonio Barragan fouled Costa in the area before the striker found the top corner with his second spot-kick.

Earlier Real Sociedad bounced back from their Champions League exit with a resounding 5-1 win over bottom side Real Betis while Sevilla and Athletic Bilbao shared the spoils in a 1-1 draw.

Bilbao, fresh from beating Barcelona last time out, were looking to consolidate fourth place but conceded an early goal from Alberto Moreno, who finished well from the edge of the area after four minutes.

Athletic were level moments later when Gaizka Toquero picked up a short back-pass from Federico Fazio and crossed for Markel Susaeta to prod the ball home from close range. Sevilla had their keeper, Beto, to thank when he saved a penalty at the end of the first half.

Bilbao stayed fourth on 30 points and Sevilla, who came into the game on the back of three league wins, climbed to seventh on 23.

Sociedad lie sixth with 26 points and Betis are two points adrift at the foot of the table with 10 points. The Basque side struggled with the demands of Europe's top competition, picking up only one point from their group, but they put the disappointment behind them with their third successive league win.

Imanol Agirretxe scored the first of his two goals early on for the hosts before Jorge Molina equalised for Betis after 19 minutes. Ion Ansotegi headed Sociedad back in front soon after the break and Betis's misery was compounded through further second-half goals by Antoine Griezmann, Agirretxe and Xabi Prieto.
