Salomon Kalou scored twice and set up another Saturday in Chelsea's 5-0 romp at Middlesbrough to maintain the Blues' high-scoring title charge in the Premier League. Dirk Kuyt scored his first two league goals at Anfield since April 2007 as Liverpool twice came from behind to beat Wigan 3-2 and stay level on points with Chelsea. Arsenal also trailed at home to Everton only to rally with a 3-1 victory and move to third. Manchester United outplayed West Bromwich Albion 4-0 to move to fourth. That means the traditional top four are in the leading positions for the first time this season. Wayne Rooney's scoring streak continued, netting the first at Old Trafford for his eighth goal in six games. Cristiano Ronaldo, Dimitar Berbatov and Nani also scored as United moved to six points behind the leaders but with a game in hand. Luiz Felipe Scolari's Chelsea has scored 11 times in four away games and has not conceded a goal home or away in five league or cup games since the 1-1 draw at home to Manchester United on Sept. 21. The goal rush started in the 14th minute when Juliano Belletti's shot took two deflections off Boro defenders in a crowded area and dropped for Kalou to shoot home from 12 meters. The second goal came in the 52nd minute when Belletti fired a 30-meter shot into the goal. A minute later, Florent Malouda pulled the ball back to Kalou, whose shot first struck defender David Wheater and deflected past the goalkeeper. Frank Lampard added the fourth with a diving header from Kalou's cross in the 63rd minute after left back Andrew Taylor had given the ball away. The fifth came four minutes later when goalkeeper Ross Turnbull fumbled Nicolas Anelka's shot, the ball bounced onto the post and Malouda stabbed it into an empty net. The results mean that Chelsea and Liverpool have 20 points from 8 games but the Blues have a far superior goal difference of 16 to the Reds' seven. Arsenal has four points to make up. Leon Osman gave Everton a ninth minute lead at Arsenal which hit back with three goals in the second half. Samir Nasri equalized in the 48th, Robin van Persie headed Arsenal in front in the 70th and Theo Walcott added the third. Aston Villa and Portsmouth drew 0-0 with Pompey's Sean Davies being sent off for a second yellow card. There was also crowd trouble at Villa Park, where linesman Phil Sharp was hit on the head by an object thrown from the stands. There were also 0-0 draws at Bolton-Blackburn and Fulham-Sunderland. Wolves went back to the top of the League Championship after a 2-1 victory over Coventry and Birmingham slipped to second after being held 1-1 at Burnley. Celtic goes clear of Rangers Scott Brown and Glenn Loovens scored to give Celtic a 2-1 victory at Inverness on Saturday and open a three-point lead over Rangers in the Scottish league title race.
