Manchester United beat Arsenal 3-1 Sunday to stay within a point of leader Chelsea after its first ever Premier League win at Emirates Stadium. Nani set up two goals in five first-half minutes, one an own-goal by goalkeeper Manuel Almunia and the other by Wayne Rooney, before Park Ji-sung carried the ball half the length of the field to make it 3-0 in the 52nd minute. United's second win of the season over Arsenal took its unbeaten record against the Gunners to five matches and pushed the defending champion to 53 points. United looked confident throughout after reaching the League Cup final this week with a 3-1 win over Manchester City. Arsenal, which only scored with 10 minutes left when Thomas Vermaelen's shot deflected off defender Jonny Evans, is in third place on 49 points after its first Premier League defeat since November. Manchester City is eight points back from Arsenal in sixth place after beating last-place Portsmouth 2-0, although City could easily climb higher since it has played two fewer matches than the four sides immediately above it. United took control with its 33rd-minute opener and could have won by a bigger margin, with Nani and Rooney both going close to scoring more. Nani created United's first goal when he danced between two defenders on the right touchline, dodged a third on the edge of the area and floated a cross from a narrow angle toward the far post. With Park rushing in behind for what would have been an easy finish, Almunia tried to flick the ball over the bar but pushed it into the net. Nani then played an integral role in the length-of-the-field counterattack that ended with Rooney calmly shooting past Almunia for his 100th Premier League goal. Arsenal's defense disintegrated as Park charged from inside his own half to score before Vermaelen finally roused a dispirited home crowd with his late goal. Emmanuel Adebayor and Vincent Kompany scored first-half goals to put Manchester City level on points with Liverpool and just one point behind fourth-place Tottenham. Juventus drops points Juventus' troubles continued with a 1-1 draw at home with Lazio Sunday in new coach Alberto Zaccheroni's debut. Alessandro Del Piero put Juventus in front with a penalty kick in the 70th minute following a dubious foul, but Stefano Mauri equalized for Lazio eight minutes later. It was Juve's fifth consecutive game without a victory, including a 2-1 loss to Inter Milan Thursday that eliminated the Turin team from the Italian Cup. On Friday, Zaccheroni was hired to replace Ciro Ferrara. Juve moved into a tie for fifth with Palermo with 34 points each, 15 behind leader Inter. Earlier, AS Roma extended its unbeaten run to 17 games with a 2-1 win over last-place Siena, moving into a tie for second with AC Milan, which was held to a 1-1 draw at the San Siro by Livorno. Inter Milan's game at Parma was postponed until Feb. 10 due to snow covering the stands at the Tardini stadium. Inter leads with 49 points and Roma and Milan are next with 41 points apiece. Also Sunday, it was: Cagliari 2, Fiorentina 2; Catania 1, Udinese 1; Chievo Verona 1, Bologna 1; and Sampdoria 2, Atalanta 0. – APPremier League table P W D L F A Pts 1 Chelsea 23 17 3 3 57 19 54 2 Man.
