Samuel Eto'o scored a hat trick inside the first 24 minutes as Barcelona powered to the summit of the Spanish First Division with a 5-0 win over 10-man Almeria on Saturday. Barcelona replaces Valencia, which plays at Recreativo Huelva on Sunday, at the top on goal difference after a scintillating display which saw the host score five times in the first half. Cameroon international Eto'o opened the scoring after just four minutes and Frenchman Thierry Henry netted on 13 minutes after brilliant play from Lionel Messi. The floodgates opened on 20 minutes when Eto'o scored his second and his quick-fire hat trick was completed four minutes later. Eto'o becomes the league's top-scorer with nine goals after his treble - he now has one goal more than Valencia's David Villa. Almeria's cause was not helped when striker Alvaro Negredo was dismissed for a crude challenge on the half hour mark and shortly afterwards Brazilian international Dani Alves scored his first Barca league goal from a free-kick. A half-time standing ovation from the Camp Nou greeted the smiling Barca players while Almeria's players trudged off. Barca continue to plunder the goals having recently crushed Atletico Madrid 6-1 - when it led 5-1 at the break - and it also demolished FC Basel 5-0 in midweek in the Champions League. It was a sixth straight win in the league for Barca and a ninth successive win in all competitions. Barca's title rivals are now under pressure to respond with reigning champion Real Madrid, three points behind, looking to bounce back from its 2-1 Champions League defeat to Juventus with victory over Athletic Bilbao on Sunday. Valencia, level on points with Barca, travels to Recreativo while fourth-placed Villarreal, two points behind, hosts Atletico Madrid at El Madrigal on Sunday in the game of the weekend. Sevilla is in third, level on points with Villarreal, going into Sunday's home match against Malaga. Earlier Saturday, Osasuna's miserable start to the season continued with a 2-0 home loss to Real Betis with Turkish international Mehmet Aurelio and Argentine Hugo Pavone on target. Betis climbs to 12th with its second win of the campaign while Osasuna stays second from bottom. Juventus wins Turin derby In Italy, Brazilian forward Amauri scored in the 48th minute to lead Juventus over Torino 1-0 Saturday for its first league victory in more than a month. Amauri dribbled by a defender and scored his fifth goal of the season in the Turin derby with an angled shot, aided by a poor saving attempt by goalkeeper Alex Calderoni, who was filling in for injured Matteo Sereni. Calls were being made for coach Claudio Ranieri to be fired following a loss to Napoli last weekend, but now Juve has won two big games in five days - including its 2-1 win over Real in the Champions League. With 12 points, Juventus moved back into the top half of the table. Also, Catania drew 1-1 at Siena to move within one point of leader Inter Milan, which leads with 16 points.
