Manchester United recovered from its shock midweek defeat with a 5-0 Premier League win at Wigan, while Arsenal continued its strong start to the season by beating visiting Portsmouth 4-1. Wayne Rooney hit his 100th and 101st club goals and Michael Owen struck his first to help give defending champion United the victory it desperately wanted after Wednesday's 1-0 loss at newly promoted Burnley. Victory kept United, which is chasing a record fourth straight title, level with Arsenal on six points, but the Gunners have played two games to United's three ahead of the teams' meeting next weekend. Manchester City kept pace on six points after Emmanuel Adebayor scored for the second straight match to give his new team a 1-0 win over Wolverhampton Wanderers, while Sunderland and Hull also won. The win moved United up among the pack at the top of the Premier League, although Tottenham and Chelsea both have the chance to go three points clear when they play Sunday. Arsenal still looks to be the team in form after it followed an opening 6-1 win at Everton and 2-0 Champions League qualifying win at Celtic with a big win over struggling Portsmouth. Abou Diaby scored twice before defender Younes Kaboul got a goal back in the 37th, but William Gallas and Aaron Ramsey added second-half goals to make the Gunners the league's top scorers. Former Arsenal striker Adebayor got Manchester City's only goal against newly promoted Wolves with a low right-foot shot, while Hull rebounded from Wednesday's 5-1 home loss to Tottenham with a first home win in the league since December. Kenwyne Jones scored twice to give Sunderland a 2-1 win over Bolton, which has yet to win a game, while Birmingham and Stoke drew 0-0 in the day's other match. Pato lifts Milan spirits Alexandre Pato scored twice to lead AC Milan to a 2-1 victory over Siena on Saturday and give new coach Leonardo a winning start to the Serie A season. Milan had struggled in the preseason with seven losses in eight games, but Pato's goals in the 29th and 48th minutes provided a fairly comfortable win. Abled Ghezzal had equalized for Siena in the 34th. The 19-year-old Pato, who scored 15 goals last season, thought he had his first of this campaign with a header in the 22nd minute, but he was offside from Ronaldinho's free kick. However, he made no mistakes seven minutes later when played through by his fellow Brazilian, lifting the ball over Siena goalkeeper Gianluca Curci. The lead didn't last long, as Marco Storari could only parry Lukas Jarolim's shot and Ghezzal hit home the rebound. But Pato put Milan back ahead for good after Ronaldinho picked out Mathieu Flamini in the area, who crossed to Pato for an easy tap-in into the unguarded net. In Saturday's other match, Bologna's Paolo Osvaldo scored the first goal of the new season in a 1-1 draw at home against Fiorentina.
