Zlatan Ibrahimovic scored four minutes after coming on as a substitute Sunday to lead Barcelona to a 1-0 victory over Real Madrid and send the defending champion to the top of the Spanish league standings. Moments after Barcelona's defense had denied a Gonzalo Higuain effort, Daniel Alves found Ibrahimovic at the far post with a lofted cross in the 56th minute and the Sweden striker never broke stride as he volleyed past Iker Casillas with his left foot. Cristiano Ronaldo, making his first start in two months in the season's highly-anticipated Spanish “clasico” match, had Madrid's best chance in the 20th minute, but was denied by Victor Valdes. Barcelona leads the standings with 30 points, overtaking Madrid on 28. Sevilla is third with 26, followed by Valencia and Deportivo La Coruna, who are both on 25 points. Deportivo La Coruna jumped to fifth place with 22 points with a 1-0 win at Racing Santander, while Athletic Bilbao maintained its recent strong form with a 4-1 win over Almeria 4-1. Atletico Madrid climbed out of the relegation zone by beating Espanyol 4-0. Also, Roberto Soldado scored his second hat trick of the season to lead Getafe 5-1 over Xerez, Tenerife hit back from 3-0 down to draw 3-3 against Valladolid and Osasuna beat Zaragoza 1-0. Chelsea on song Chelsea regained its dominant place in the Premier League title race with a 3-0 win at the Emirates Sunday that restored its five-point lead over Manchester United. Two goals from Didier Drogba and a Thomas Vermaelen own goal made the difference as Arsenal was left 11 points off the pace. Chelsea tops the standings on 36 points, five clear of United. Tottenham Hotspur is third on 26 with Arsenal fourth on 25 and Liverpool, which won 2-0 at Everton Sunday, fifth on 23. In the day's other big derby Liverpool ended a bleak week on a high note with a morale-lifting victory. Liverpool took a fortunate early lead when Javier Mascherano's speculative shot was deflected past Tim Howard by Everton defender Joseph Yobo. Hard-working Everton had two goals ruled out for offside and was then denied by a great double-save by Pepe Reina before Dirk Kuyt finished it 10 minutes from time, seizing on Howard's parry of an Alberto Riera shot after another Yobo blunder. Leverkusen on top Stefan Kiessling scored hat trick Sunday to lead Bayer Leverkusen to a 4-0 win over Stuttgart to reclaim first place in the Bundesliga. The win gave undefeated Leverkusen 30 points, three more than Werder Bremen after 14 rounds, while Kiessling raised his league-high season total to 12 goals. In the late match Sunday, Ivica Olic scored one goal and set up another as Bayern Munich won 3-0 in Hannover to move into fourth place with 24 points. Schalke is third on 25. Inter 7 points clear Diego Milito's penalty five minutes from time gave Inter Milan a deserved 1-0 home win over Fiorentina Sunday and extended its Serie A lead to seven points. AC Milan rose to second after substitute Klaas Jan Huntelaar netted his first two goals for the club deep into injury time to seal a 2-0 win at Catania. Juventus slipped to third after losing 2-0 at Cagliari despite dominating for spells. Promoted Parma moved up to joint fourth with Sampdoria, thanks to a 1-1 home draw with Napoli. Other results: Bari 2 Siena 1; Roma 2 Atalanta 1; Lazio 0 Bologna 0; Chievo 1 Palermo 0.
