Arsenal [ Images ] rediscovered their Premier League form on Saturday with a convincing 3-0 victory over Newcastle United at the Emirates Stadium.

Portsmouth ended a run of six successive league defeats when they won 3-0 at Everton while Hull City's flying start ended emphatically when they were thrashed 5-0 at home by Wigan Athletic.

Chelsea [ Images ] face Tottenham Hotspur [ Images ] on Sunday, when Liverpool are in action at Aston Villa [ Images ], while champions Manchester United [ Images ] take a break after playing in the European Super Cup on Friday.

In Saturday's other games, West Ham United beat Blackburn Rovers 4-1, Middlesbrough beat Stoke City [ Images ] 2-1 and Bolton Wanderers' game against West Bromwich Albion [ Images ] finished goalless.

Arsenal were poor when losing at Fulham [ Images ] last week but were always in control on home soil.

A Charles N'Zogbia handball enabled Robin van Persie [ Images ] to put them ahead with an 18th-minute penalty and the Dutchman got his second five minutes before halftime when he ended a flowing move with a searing shot into the roof of the net.

Another fluid passing movement ended with Denilson tucking in the third.

FA Cup winners Portsmouth last tasted a league victory against West Ham on April 8 and started the new season with two defeats, albeit against Chelsea and Manchester United.

DEFOE STRIKES

They began well on Saturday though when Jermain Defoe [ Images ] turned well to put them ahead after 11 minutes and a rare effort by defender Glen Johnson made it 2-0 by halftime.

David James [ Images ] saved a Yakubu Aiyegbeni penalty early in the second half and Portsmouth finished with a flourish when a Defoe chip came down off the bar and just over the line, though Crouch was on hand to make doubly sure.

"We played a new system (using wingbacks), the players have worked hard on it all week and that result should give them a lot of belief," Portsmouth manager Harry Redknapp [ Images ] told Sky Sports News.

"I've been wanting to do it for a long time, we've got the personnel to do it with pace at the back and two attacking fullbacks."

Hull began their first season in the top flight with a win and a draw but were thumped by a Wigan team who started with two defeats.

An early own goal, a breakaway by Antonio Valencia and, after the break, two for Amr Zaki and one for Emile Heskey in the second half did the damage.

"It was a harsh reality check," said Hull coach Phil Brown. "If I said we looked a decent side today I'd be a foolish man.

"We had a lot of chances and missed them all while Wigan had five shots on target and scored five."
