Diego Costa and David Villa delivered again for Atletico Madrid, whose Spanish league title charge continued to gain strength Sunday with a 2-0 victory over Athletic Bilbao.
Villa enjoyed Atletico's best opportunities at the Vicente Calderon Stadium and put the hosts ahead after 32 minutes by volleying Juanfran's headed-on cross through the crowded area into goal.
Nine minutes later, Koke delivered a perfect ball to Costa, who the cut back to dribble around Erik Moran and fire a low shot beyond goalkeeper Gorka Iraizoz for his joint league-leading 13th goal of the season.
Bilbao rarely threatened and was reduced to 10 men in the 81st when Moran was shown a second yellow.
Atletico's 11th win in 12 rounds left it one point behind leader Barcelona, which has 34 points.
