Premier League - Watch all the weekend's goals
Miss any of this weekend's 22 goals in the Barclays Premier League? Watch them all here.
Manchester United stole Manchester City's thunder again when a Wayne Rooney treble sparked a 5-0 rout of Bolton Wanderers after their neighbours had breezed past Wigan Athletic 3-0 with a hat-trick from Sergio Aguero.
Champions United were three goals up after 25 minutes thanks to one from Javier Hernandez, making his first start of the season, and two from Rooney who has scored in every Premier League game this term.
Hernandez added another for the visitors in the 58th minute before Rooney struck his third 10 minutes later to complete back-to-back league hat-tricks.
"They (Rooney and Hernandez) are a constant threat. Their movement and the pace they play at was really first class for us today," manager Alex Ferguson said.
Like two weeks ago, when City recorded a 5-1 win at Tottenham Hotspur only to be trumped by United's 8-2 thrashing of Arsenal, Ferguson's side outgunned Roberto Mancini's team to sit top of the table above City on goal difference.
City prospered against Wigan thanks to Argentina forward Aguero who has six goals in four games for his new club but any headlines he might have received were soon overtaken by United's masterclass at Bolton.
Hernandez opened the scoring in the fifth minute with the type of finish that was a hallmark of his debut season last year, making a fantastic run into the box to get an outstretched leg to Nani's cross from the right.
Two quick goals by Rooney, both deft touches set up by defender Phil Jones, put United three up at the break as Bolton's defence fell apart.
Hernandez, who missed the start of the campaign after suffering concussion on a pre-season tour, showed last term's great form was no fluke as he slotted in from close range after Bolton failed to clear in the 58th minute.
Rooney completed his hat-trick with a superb first-time drive after a pull-back from Nani while Hernandez missed a couple of chances to snatch his own treble.
United's day was clouded by Tom Cleverley limping off in the opening minutes with Ferguson saying the midfielder may have broken his foot after a "bad tackle" from Bolton captain Kevin Davies.
While Rooney and Ferguson said United were concentrating on their own game rather than worrying about City, fans from the blue side of Manchester will find it galling that their excellent start to the season is being eclipsed.
Displaying a more attacking brand of soccer than last season's more conservative approach, Mancini's men took just 13 minutes to get off the mark at home to Wigan with David Silva and Carlos Tevez combining well to put Aguero through.
Tevez missed a penalty and City wasted several other chances before substitute Samir Nasri, playing with a broken finger, put Aguero through with his first touch of the ball in the 63rd minute.
Six minutes later Aguero completed his hat-trick when he tucked in another through ball from Silva to give his side plenty of confidence before they make their Champions League debut at home to Napoli on Wednesday.
"Sergio is a fantastic striker, he is an incredible player, he is young, he scored three fantastic goals. He has scored always in his career and I hope it can continue here," manager Mancini said.
Fellow Champions League combatants and title hopefuls Chelsea also gave themselves a boost with a 2-1 win at Sunderland with goals from John Terry and Daniel Sturridge while Arsenal notched their first win of the season.
Arsene Wenger's side scored a 1-0 victory courtesy of a lucky Andrei Arshavin goal gifted by a blunder from Swansea City goalkeeper Michel Vorm.
Tottenham Hotspur got their first points of the season by overcoming Wolverhampton Wanderers 2-0. Liverpool's unbeaten start came to a halt when they lost 1-0 at Stoke City while Everton drew 2-2 at home to Aston Villa.
Fulham and Blackburn Rovers were still looking for their first Premier League wins of the season after battling to a 1-1 stalemate on Sunday but West Bromwich Albion got theirs with a 1-0 victory at Norwich City.
The results left Fulham and Blackburn in the bottom three after four matches, although Blackburn at least picked up their first point after three successive defeats.
Blackburn stayed bottom, one place behind Swansea City, who like Fulham have two points. West Brom, who started the day in 19th spot, leapt to 12th.
Blackburn took the lead at Craven Cottage with a stunning left-foot shot from Spaniard Ruben Rochina after 32 minutes and Bobby Zamora equalised, also with a left-foot shot, six minutes later.
The visitors finished with 10 men after Canadian youngster David "Junior" Hoillet was carried off on a stretcher after a stoppage-time collision with Fulham goalkeeper Mark Schwarzer.
"He is up on his feet and conscious but he was out for a few minutes and needs to get stitched up," Blackburn manager Steve Kean told Sky Sports.
Kean has incurred the wrath of Blackburn fans who have written an open letter for him to be sacked.
"That doesn't affect me," he said. "I've got the backing of the players and the owners and if the fans stick with us I am sure they will see many away performances like that which will give us more than one point."
West Brom picked up their first win of the season after Peter Odemwingie scored after only three minutes at Carrow Road.
The 30-year-old Nigeria international striker, back in the side after injury, took advantage of a mixup between central defender Richie de Laet and reserve goalkeeper Declan Rudd to score.
Odemwingie's second-half penalty was saved by Rudd and Norwich, back in the top flight after six years, have given away a penalty in each of their four matches this season.
All the main title contenders played on Saturday when Manchester United crushed Bolton Wanderers 5-0 and Manchester City beat Wigan Athletic 3-0 to maintain their perfect starts to the season.
