Keita treble inspires Barça
A hat-trick from Seydou Keita helped Barcelona on their way to a 6-1 defeat of Real Zaragoza as the defending champions regained their three-point lead at the top of the table. Keita struck after 25, 41 and 86 minutes at the Nou camp with Zlatan Ibrahimovic adding two more as Pep Guardiola's side ran riot.
Lionel Messi was also on the scoresheet for the home side with his goal coming two minutes after Jorge Lopez had grabbed Zaragoza's only reply. Barça remain unbeaten in the competition and continue to hold the advantage over second-placed Real Madrid.
Valencia moved into fourth place in the standings with a 3-0 victory over ten-man Almeria. Pablo Hernandez set up David Villa for his side's first, and brought about the foul that resulted in Almeria goalkeeper Diego Alves being sent off.
Hernandez then capped a fine performance with a brilliant long-range lob to double the visitors' lead with Juan Manuel Mata drilling home a low shot late on to complete a pleasing night's work for Unai Emery's men.
Two for Aleman
Nauzet Aleman scored twice as struggling Real Valladolid outplayed high-flying Deportivo La Coruna in a convincing 4-0 victory. Aleman netted a 19th-minute opener from close range and struck his second two minutes into the second half.
Diego Costa scored a third after 77 minutes before Valladolid secured a second win of the season with Haris Medunjanin's 88th-minute effort. Villarreal moved off the bottom of the table with a 2-1 win over fellow strugglers Malaga in what was a first league victory for Ernesto Valverde's side at the eighth time of asking.
Valverde saw his side go ahead through Nilmar after 27 minutes of play, and although Albert Luque equalised at the end of the first half, Villarreal took all three points thanks to a Joan Capdevila free-kick after 54 minutes.
A goal by Manuel Arana in the fifth minute of injury-time earned Racing Santander a 1-1 draw after Walter Pandiani appeared to have guided Osasuna to victory. Pandiani struck eight minutes after half-time and with just seconds to go Osasuna were on the brink of their second away win until Aruna struck to earn a vital point for the hosts.
Roberto Soldado and Dani Parejo fired second-half goals to help Getafe register a 2-0 victory over Athletic Bilbao, who lost Carlos Gurpegi and Ustaritz Aldekoaotalora to red cards at the end of either half. Alejandro Alfaro's 17th-minute goal enabled Tenerife to edge out Xerez 1-0 in a game between two promoted sides.
