LONDON — Manchester United recovered from its shocking midweek defeat with a 5-0 Premier League win at Wigan, while Arsenal defeated 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.
"You have to react to a defeat," United manager Alex Ferguson said. "We got a performance there. We had six chances in the first half and we didn't take any of them. The important thing is to have patience and we did that."
Victory kept United, which is chasing a record fourth straight title, even 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 lead his new team a 1-0 win over Wolverhampton Wanderers, while United States striker Jozy Altidore set up a goal on debut to give Hull a 1-0 win over Bolton.
Altidore came on as a 60th-minute substitute and set up a goal for Kamel Fathi Ghilas with his first touch a minute later.
"The fans will take to him," Hull manager Phil Brown said. "He's a big, bubbly character."
Manchester United has started the season slowly following the sale of Cristiano Ronaldo to Real Madrid and struggled to break down Wigan for 56 minutes on Saturday.
But former Wigan winger Antonio Valencia then crossed from the left for Rooney to head in and become the 21st player to score 100 goals for United.
Wigan then hit the bar before Rooney and Paul Scholes combined in the 58th to set up Dimitar Berbatov, who lifted the ball over goalkeeper Chris Kirkland and into the net.
Rooney made it 3-0 in the 65th with a deflected shot to move to 101 goals in 241 appearances and Owen replaced his former England teammate before beating Kirkland with a near-post shot.
"Strikers have to score," Ferguson said. "That's their mantra."
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 matches Sunday. Aston Villa is at Liverpool on Monday.
Also Saturday, it was: Sunderland 2, Bolton 1; Birmingham 0, Stoke 0.
BERLIN (AP) — Bayern Munich lost 2-1 at promoted Mainz to remain without a Bundesliga victory under new coach Louis van Gaal.
Andreas Ivanschitz and Aristide Bance scored to give Mainz the first league win over the German powerhouse, which is in 12th place with two draws and a loss.
Bayer Leverkusen cruised past promoted Freiburg 5-0 on the road and moved ahead of Schalke to top the standings. Defending champion Wolfsburg could emerge as the sole leader if it defeats Hamburger SV on Sunday.
In other games, Borussia Dortmund and Stuttgart drew 1-1, Hannover won 2-0 at FC Nuremberg under an interim coach and 10-man Eintracht Frankfurt held on for a 0-0 draw at FC Cologne.
In Mainz, the home team Bayern under pressure right away.
Ivanschitz found the target in the 25th, shooting with his left-foot from the edge of the box. Bayern goalkeeper Michael Rensing dived to his right but the ball bounced over his arm into the net.
Bance scored in the 37th after he had earlier hit the crossbar with an overhead kick and then sent a header over the top. With its defense in disarray, Bayern failed to clear a cross from Florian Heller and Bance headed past Rensing.
Bayern played better in the second half and got back into the match when Mainz's Nikolce Noveski headed into his own net in the 47th.
Without playmaker Franck Ribery, who is still not fully recovered from knee tendinitis, Bayern couldn't break through again.
Schalke and Hoffenheim drew 0-0 on Friday.
GLASGOW, Scotland (AP) — Celtic expended its winning start to the Scottish Premier League season with a 5-2 victory over visiting St. Johnstone.
Celtic, which is seeking to regain the title from rival Rangers, got two goals each from Marc-Antoine Fortune and Shaun Maloney, while Scott McDonald hit the fifth in the 74th minute.
Fortune hit his first goal since joining from Nancy in the 21st and Maloney made it 2-0 with a header.
Saints striker Collin Samuel got a goal back in the 36th but, in the second half, Maloney hit a powerful shot from the edge of the area, Fortune scored with a 14-yard shot and McDonald headed in a cross by Danny Fox.
Jody Morris got the other goal in the 76th, too late to impact the outcome of the match.
Hibernian stayed even with Celtic on six points after a 3-1 win at Falkirk, while Rangers can reach the mark if it beats Hearts on Sunday.
